Power Of Music On The Brain - Dementia \u0026 Parkinson's
Music and art can enrich the lives of people with Alzheimer's disease. Both allow for self-expression and engagement, even after dementia has progressed. Music can be powerful. Studies have shown music may reduce agitation and improve behavioral issues that are common in the middle-stages of the disease. Even in the late-stages of Alzheimer's, a person may be able to tap a beat or sing lyrics to a song from childhood. Music provides a way to connect, even after verbal communication has become difficult. Subtle problems with the executive functions of attentiveness , planning , flexibility, and abstract thinking , or impairments in semantic memory memory of meanings, and concept relationships can also be symptomatic of the early stages of Alzheimer's disease.
MCI can present with a variety of symptoms, and when memory loss is the predominant symptom, it is termed amnestic MCI and is frequently seen as a prodromal stage of Alzheimer's disease. In people with Alzheimer's disease, the increasing impairment of learning and memory eventually leads to a definitive diagnosis. In a small percentage, difficulties with language, executive functions, perception agnosia , or execution of movements apraxia are more prominent than memory problems. Older memories of the person's life episodic memory , facts learned semantic memory , and implicit memory the memory of the body on how to do things, such as using a fork to eat or how to drink from a glass are affected to a lesser degree than new facts or memories.
Language problems are mainly characterised by a shrinking vocabulary and decreased word fluency , leading to a general impoverishment of oral and written language. Progressive deterioration eventually hinders independence, with subjects being unable to perform most common activities of daily living. Reading and writing skills are also progressively lost. Behavioral and neuropsychiatric changes become more prevalent. Common manifestations are wandering , irritability and emotional lability , leading to crying, outbursts of unpremeditated aggression , or resistance to caregiving. During the final stage, known as the late-stage or severe stage, the patient is completely dependent upon caregivers.
Although aggressiveness can still be present, extreme apathy and exhaustion are much more common symptoms. People with Alzheimer's disease will ultimately not be able to perform even the simplest tasks independently; muscle mass and mobility deteriorates to the point where they are bedridden and unable to feed themselves. The cause of death is usually an external factor, such as infection of pressure ulcers or pneumonia , not the disease itself.
Alzheimer's disease is believed to occur when abnormal amounts of amyloid beta , accumulating extracellularly as amyloid plaques , and tau proteins , accumulating intracellularly as neurofibrillary tangles , form in the brain affecting neuronal functioning and connectivity, resulting in a progressive loss of brain function. These types are known as early onset familial Alzheimer's disease , can have a very early onset, and a faster rate of progression. Most cases of Alzheimer's are not inherited and are termed sporadic Alzheimer's disease, in which environmental and genetic differences may act as risk factors. Most cases of sporadic Alzheimer's disease in contrast to familial Alzheimer's disease are late-onset Alzheimer's disease LOAD developing after the age of 65 years.
APOE plays a major role in lipid-binding proteins in lipoprotein particles and the epsilon4 allele disrupts this function. Alleles in the TREM2 gene have been associated with a 3 to 5 times higher risk of developing Alzheimer's disease. Many single-nucleotide polymorphisms SNPs are associated with Alzheimer's, with a study adding 30 SNPs by differentiating Alzheimer's disease into six categories, including memory, language, visuospatial, and executive functioning. A Japanese pedigree of familial Alzheimer's disease was found to be associated with a deletion mutation of codon of APP. Only homozygotes with this mutation develop Alzheimer's disease.
Mice expressing this mutation have all the usual pathologies of Alzheimer's disease. The oldest hypothesis, on which most drug therapies are based, is the cholinergic hypothesis ,  which proposes that Alzheimer's disease is caused by reduced synthesis of the neurotransmitter acetylcholine. The cholinergic hypothesis has not maintained widespread support, largely because medications intended to treat acetylcholine deficiency have not been very effective. While apolipoproteins enhance the breakdown of beta amyloid, some isoforms are not very effective at this task such as APOE4 , leading to excess amyloid buildup in the brain. The tau hypothesis proposes that tau protein abnormalities initiate the disease cascade.
Eventually, they form neurofibrillary tangles inside nerve cell bodies. A number of studies connect the misfolded amyloid beta and tau proteins associated with the pathology of Alzheimer's disease, as bringing about oxidative stress that leads to chronic inflammation. Sleep disturbances are seen as a possible risk factor for inflammation in Alzheimer's disease. Sleep problems have been seen as a consequence of Alzheimer's disease but studies suggest that they may instead be a causal factor.
Sleep disturbances are thought to be linked to persistent inflammation. Cholesterol signaling hypothesis postulates that amyloid production and tau phosphorylation are regulated by cholesterol and high brain cholesterol contributes to the disease. First, the cholesterol is made in the astrocytes, the astrocytes load the cholesterol into the cholesterol carrier protein apoE , and the apoE loads the cholesterol into the neurons.
Once in the neurons, cholesterol causes clustering of amyloid precursor protein APP with its hydrolytic enzyme gamma secretase, resulting in amyloid beta production and accumulation of amyloid plaques. A neurovascular hypothesis stating that poor functioning of the blood—brain barrier may be involved has been proposed. The cellular homeostasis of biometals such as ionic copper, iron, and zinc is disrupted in Alzheimer's disease, though it remains unclear whether this is produced by or causes the changes in proteins. These ions affect and are affected by tau, APP, and APOE,  and their dysregulation may cause oxidative stress that may contribute to the pathology.
Smoking is a significant Alzheimer's disease risk factor. There is tentative evidence that exposure to air pollution may be a contributing factor to the development of Alzheimer's disease. One hypothesis posits that dysfunction of oligodendrocytes and their associated myelin during aging contributes to axon damage, which then causes amyloid production and tau hyper-phosphorylation as a side effect. Retrogenesis is a medical hypothesis about the development and progress of Alzheimer's disease proposed by Barry Reisberg in the s. The association with celiac disease is unclear, with a study finding no increase in dementia overall in those with CD, while a review found an association with several types of dementia including Alzheimer's disease.
Kynurenines are a downstream metabolite of tryptophan and have the potential to be neuroactive. This may be associated with the neuropsychiatric symptoms and cognitive prognosis in mild dementia. A five-year study focused on the role of kynurenine in Alzheimer's and Lewy body disease and found its increase to be associated with more hallucinations. Alzheimer's disease is characterised by loss of neurons and synapses in the cerebral cortex and certain subcortical regions. This loss results in gross atrophy of the affected regions, including degeneration in the temporal lobe and parietal lobe , and parts of the frontal cortex and cingulate gyrus. Tangles neurofibrillary tangles are aggregates of the microtubule-associated protein tau which has become hyperphosphorylated and accumulate inside the cells themselves.
Although many older individuals develop some plaques and tangles as a consequence of aging, the brains of people with Alzheimer's disease have a greater number of them in specific brain regions such as the temporal lobe. Alzheimer's disease has been identified as a protein misfolding disease , a proteopathy , caused by the accumulation of abnormally folded amyloid beta protein into amyloid plaques, and tau protein into neurofibrillary tangles in the brain. Amyloid beta is a fragment from the larger amyloid-beta precursor protein APP a transmembrane protein that penetrates the neuron's membrane.
APP is critical to neuron growth, survival, and post-injury repair. Alzheimer's disease is also considered a tauopathy due to abnormal aggregation of the tau protein. Every neuron has a cytoskeleton , an internal support structure partly made up of structures called microtubules. These microtubules act like tracks, guiding nutrients and molecules from the body of the cell to the ends of the axon and back.
A protein called tau stabilises the microtubules when phosphorylated , and is therefore called a microtubule-associated protein. In Alzheimer's disease, tau undergoes chemical changes, becoming hyperphosphorylated ; it then begins to pair with other threads, creating neurofibrillary tangles and disintegrating the neuron's transport system. Exactly how disturbances of production and aggregation of the beta-amyloid peptide give rise to the pathology of Alzheimer's disease is not known. Accumulation of aggregated amyloid fibrils , which are believed to be the toxic form of the protein responsible for disrupting the cell's calcium ion homeostasis , induces programmed cell death apoptosis. Various inflammatory processes and cytokines may also have a role in the pathology of Alzheimer's disease.
Inflammation is a general marker of tissue damage in any disease, and may be either secondary to tissue damage in Alzheimer's disease or a marker of an immunological response. Obesity and systemic inflammation may interfere with immunological processes which promote disease progression. Alterations in the distribution of different neurotrophic factors and in the expression of their receptors such as the brain-derived neurotrophic factor BDNF have been described in Alzheimer's disease.
Alzheimer's disease is usually diagnosed based on the person's medical history , history from relatives, and behavioral observations. The presence of characteristic neurological and neuropsychological features and the absence of alternative conditions is supportive. Assessment of intellectual functioning including memory testing can further characterise the state of the disease. The diagnosis can be confirmed with very high accuracy post-mortem when brain material is available and can be examined histologically. A histopathologic confirmation including a microscopic examination of brain tissue is required for a definitive diagnosis. Good statistical reliability and validity have been shown between the diagnostic criteria and definitive histopathological confirmation.
Neuropsychological tests including cognitive tests such as the Mini—Mental State Examination MMSE are widely used to evaluate the cognitive impairments needed for diagnosis. More comprehensive test arrays are necessary for high reliability of results, particularly in the earliest stages of the disease. Further neurological examinations are crucial in the differential diagnosis of Alzheimer's disease and other diseases.
Caregivers can supply important information on the daily living abilities, as well as on the decrease, over time, of the person's mental function. Supplemental testing provides extra information on some features of the disease or is used to rule out other diagnoses. Blood tests can identify other causes for dementia than AD  —causes which may, in rare cases, be reversible. It is also necessary to rule out delirium. Psychological tests for depression are employed, since depression can either be concurrent with Alzheimer's disease see Depression of Alzheimer disease , an early sign of cognitive impairment,  or even the cause. Due to low accuracy, the C-PIB-PET scan is not recommended to be used as an early diagnostic tool or for predicting the development of Alzheimer's disease when people show signs of mild cognitive impairment MCI.
There is no evidence that supports any particular measure as being effective in preventing Alzheimer's disease. Epidemiological studies have proposed relationships between certain modifiable factors, such as diet, cardiovascular risk, pharmaceutical products, or intellectual activities, among others, and a population's likelihood of developing Alzheimer's disease. Only further research, including clinical trials, will reveal whether these factors can help to prevent Alzheimer's disease. Cardiovascular risk factors, such as hypercholesterolaemia , hypertension , diabetes , and smoking , are associated with a higher risk of onset and worsened course of Alzheimer's disease.
Long-term usage of non-steroidal anti-inflammatory drugs NSAIDs were thought in to be associated with a reduced likelihood of developing Alzheimer's disease. Evidence suggests that higher education and occupational attainment, and participation in leisure activities show a reduced risk of developing Alzheimer's,  or of delaying the onset of symptoms. This is compatible with the cognitive reserve theory, which states that some life experiences result in more efficient neural functioning providing the individual a cognitive reserve that delays the onset of dementia manifestations.
Physical exercise is associated with decreased rate of dementia. Diet is seen to be a modifiable risk factor for the development of dementia. A different approach has been to incorporate elements of both of these diets into one known as the MIND diet. Raised blood sugar levels over a long time, can damage nerves and cause memory problems if they are not managed. The MIND diet may be more protective but further studies are needed.
The Mediterranean diet seems to be more protective against Alzheimer's than DASH but there are no consistent findings against dementia in general. The role of olive oil needs further study as it may be one of the most important components in reducing the risk of cognitive decline and dementia. In those with celiac disease or non-celiac gluten sensitivity , a strict gluten-free diet may relieve the symptoms given a mild cognitive impairment. Conclusions on dietary components have been difficult to ascertain as results have differed between population-based studies and randomised controlled trials. Curcumin as of [update] had not shown benefit in people even though there is tentative evidence in animals. However, further population studies are recommended to see this use beyond experimental.
There is no cure for Alzheimer's disease; available treatments offer relatively small symptomatic benefits but remain palliative in nature. Current treatments can be divided into pharmaceutical, psychosocial, and caregiving. Medications used to treat the cognitive problems of Alzheimer's disease include: four acetylcholinesterase inhibitors tacrine , rivastigmine , galantamine , and donepezil and memantine , an NMDA receptor antagonist. The benefit from their use is small. Reduction in the activity of the cholinergic neurons is a well-known feature of Alzheimer's disease. Glutamate is an excitatory neurotransmitter of the nervous system , although excessive amounts in the brain can lead to cell death through a process called excitotoxicity which consists of the overstimulation of glutamate receptors.
Excitotoxicity occurs not only in Alzheimer's disease, but also in other neurological diseases such as Parkinson's disease and multiple sclerosis. It acts on the glutamatergic system by blocking NMDA receptors and inhibiting their overstimulation by glutamate. An extract of Ginkgo biloba known as EGb has been widely used for treating Alzheimer's and other neuropsychiatric disorders. EGb is the only one that showed improvement of symptoms in both Alzheimer's disease and vascular dementia. EGb is seen as being able to play an important role either on its own or as an add-on particularly when other therapies prove ineffective.
Many studies of its use in mild to moderate dementia have shown it to significantly improve cognitive function, activities of daily living, and neuropsychiatric symptoms. However, its use has not been shown to prevent the progression to dementia. Atypical antipsychotics are modestly useful in reducing aggression and psychosis in people with Alzheimer's disease, but their advantages are offset by serious adverse effects, such as stroke , movement difficulties or cognitive decline.
Psychosocial interventions are used as an adjunct to pharmaceutical treatment and can be classified within behavior-, emotion-, cognition- or stimulation-oriented approaches. Research on efficacy is unavailable and rarely specific to Alzheimer's disease, focusing instead on dementia in general. Behavioral interventions attempt to identify and reduce the antecedents and consequences of problem behaviors. This approach has not shown success in improving overall functioning,  but can help to reduce some specific problem behaviors, such as incontinence. Emotion-oriented interventions include reminiscence therapy , validation therapy , supportive psychotherapy , sensory integration , also called snoezelen , and simulated presence therapy.
A Cochrane review has found no evidence that this is effective. A review of the effectiveness of RT found that effects were inconsistent, small in size and of doubtful clinical significance, and varied by setting. There is partial evidence indicating that SPT may reduce challenging behaviors. There is no evidence to support the usefulness of these therapies. The aim of cognition-oriented treatments, which include reality orientation and cognitive retraining , is the reduction of cognitive deficits.
Reality orientation consists of the presentation of information about time, place, or person to ease the understanding of the person about its surroundings and his or her place in them. On the other hand, cognitive retraining tries to improve impaired capacities by exercising mental abilities. Both have shown some efficacy improving cognitive capacities,  although in some studies these effects were transient and negative effects, such as frustration, have also been reported. Stimulation-oriented treatments include art , music and pet therapies, exercise , and any other kind of recreational activities. Stimulation has modest support for improving behavior, mood, and, to a lesser extent, function. Nevertheless, as important as these effects are, the main support for the use of stimulation therapies is the change in the person's routine.
Since Alzheimer's has no cure and it gradually renders people incapable of tending to their own needs, caregiving is essentially the treatment and must be carefully managed over the course of the disease. During the early and moderate stages, modifications to the living environment and lifestyle can increase patient safety and reduce caretaker burden. In such cases, the medical efficacy and ethics of continuing feeding is an important consideration of the caregivers and family members. As the disease progresses, different medical issues can appear, such as oral and dental disease , pressure ulcers , malnutrition , hygiene problems, or respiratory , skin , or eye infections. Careful management can prevent them, while professional treatment is needed when they do arise.
The early stages of Alzheimer's disease are difficult to diagnose. A definitive diagnosis is usually made once cognitive impairment compromises daily living activities, although the person may still be living independently. The symptoms will progress from mild cognitive problems, such as memory loss through increasing stages of cognitive and non-cognitive disturbances, eliminating any possibility of independent living, especially in the late stages of the disease.
Life expectancy of people with Alzheimer's disease is reduced. Other coincident diseases such as heart problems , diabetes or history of alcohol abuse are also related with shortened survival. Pneumonia and dehydration are the most frequent immediate causes of death brought by Alzheimer's disease, while cancer is a less frequent cause of death than in the general population. Two main measures are used in epidemiological studies: incidence and prevalence. Incidence is the number of new cases per unit of person-time at risk usually number of new cases per thousand person-years ; while prevalence is the total number of cases of the disease in the population at any given time.
Regarding incidence, cohort longitudinal studies studies where a disease-free population is followed over the years provide rates between 10 and 15 per thousand person-years for all dementias and 5—8 for Alzheimer's disease,   which means that half of new dementia cases each year are Alzheimer's disease. Advancing age is a primary risk factor for the disease and incidence rates are not equal for all ages: every five years after the age of 65, the risk of acquiring the disease approximately doubles, increasing from 3 to as much as 69 per thousand person years.
The prevalence of Alzheimer's disease in populations is dependent upon different factors including incidence and survival. Since the incidence of Alzheimer's disease increases with age, it is particularly important to include the mean age of the population of interest. In the United States, Alzheimer's prevalence was estimated to be 1. The ancient Greek and Roman philosophers and physicians associated old age with increasing dementia. He followed her case until she died in when he first reported publicly on it. For most of the 20th century, the diagnosis of Alzheimer's disease was reserved for individuals between the ages of 45 and 65 who developed symptoms of dementia. The terminology changed after when a conference on Alzheimer's disease concluded that the clinical and pathological manifestations of presenile and senile dementia were almost identical, although the authors also added that this did not rule out the possibility that they had different causes.
Eventually, the term Alzheimer's disease was formally adopted in medical nomenclature to describe individuals of all ages with a characteristic common symptom pattern, disease course, and neuropathology. Dementia, and specifically Alzheimer's disease, may be among the most costly diseases for society in Europe and the United States,   while their costs in other countries such as Argentina,  and South Korea,  are also high and rising.
These costs will probably increase with the aging of society, becoming an important social problem. AD-associated costs include direct medical costs such as nursing home care , direct nonmedical costs such as in-home day care , and indirect costs such as lost productivity of both patient and caregiver. Costs increase with dementia severity and the presence of behavioral disturbances,  and are related to the increased caregiving time required for the provision of physical care. Economic evaluations of current treatments have shown positive results. The role of the main caregiver is often taken by the spouse or a close relative.
Dementia caregivers are subject to high rates of physical and mental disorders. Cognitive behavioral therapy and the teaching of coping strategies either individually or in group have demonstrated their efficacy in improving caregivers' psychological health. Alzheimer's disease has been portrayed in films such as: Iris , based on John Bayley 's memoir of his wife Iris Murdoch;  The Notebook , based on Nicholas Sparks ' novel of the same name ;  A Moment to Remember ; Thanmathra ;  Memories of Tomorrow Ashita no Kioku , based on Hiroshi Ogiwara's novel of the same name;  Away from Her , based on Alice Munro 's short story " The Bear Came over the Mountain ";  Still Alice , about a Columbia University professor who has early onset Alzheimer's disease, based on Lisa Genova 's novel of the same name and featuring Julianne Moore in the title role.
In early , a trial of verubecestat , which inhibits the beta-secretase protein responsible for creating beta-amyloid protein was discontinued as an independent panel found "virtually no chance of finding a positive clinical effect". It has a marked increase in oxidative stress in the brain. Medications that reduce oxidative stress have been shown to improve memory. This process begets increased amyloid-beta, which further damages mitochondria. Research on the effects of meditation on preserving memory and cognitive functions is at an early stage. The ketogenic diet is a very high-fat, adequate-protein, low-carbohydrate diet that is used to treat refractory epilepsy in children.
Designed to mimic some of the effects of fasting, following a ketogenic diet leads to elevated blood levels of molecules called ketone bodies : a metabolic state known as ketosis. These ketone bodies have a neuroprotective effect on aging brain cells, though it is not fully understood why. Limited research in the form of preclinical trials mice and rats , and small-scale clinical human trials, have explored its potential as a therapy for neurodegenerative disorders like Alzheimer's disease. The herpes simplex virus HSV-1 has been found in the same areas as amyloid plaques.
Fungal infection of Alzheimer's disease brain has also been described. Carrasco when his group found statistical correlation between disseminated mycoses and Alzheimer's disease. The slow progression of Alzheimer's disease fits with the chronic nature of some systemic fungal infections, which can be asymptomatic and thus, unnoticed and untreated. Moir and R. Will the center evaluate the person's needs? How will this evaluation be accomplished?
How often will it be repeated? Is staff trained in dementia issues? What types of health care professionals are on staff? How do you screen them? How are emergency situations handled? How do you ensure the safety of the participants? Is transportation available? Many centers offer services on sliding scales, where caregivers pay according to ability or income. In some states, Medicaid covers cost for people with very low income and few assets. Be sure to ask about basic fees, financial assistance and additional charges for such services as crafts or field trips.Cognitive training to protect immune systems of older caregivers.
