Personality changes be popular and r individuallying from apathy to uneasy agitation Psychiatric symptoms , including depression , delusions , and hallucinations , whitethorn also clear during the running of AD . AD is the ab off common give of dementia in adults . The clinical manifestations of AD stem from disfunction and death of neurons in the whizz . The hallmarks of AD are muscular structures , called neurofibrillary tangles , found in dying neurons , and ancient plaques composed of degenerating nerve-cell elements adjoin a core of granulose protein . The separate of the brain that read cognition are specially stirred , whereas regions that primarily get word sensations and control muscular driveway are generally spared . biochemical insaneities associated with neuron failure take collection of aluminum in senile plaques and tangled neurons disposition of amyloid protein in cerebral blood vessels and senile plaques disrupt nerve-cell-membrane phospholipids metabolism and decreases in Neurotransmitter substances such(prenominal)(prenominal) as tostatin Definitive diagnosing of AD is only practical through autopsy , although antielectron expelling tomography has proved helpful as symptomatic barb (see Alzheimer s disease . Grolier of encyclopedia of knowledge . Vol . 1Although the cause of AD is non known , two encounter factors digest been identified : go age and genetic sensibility .

In patients with familial AD , immediate-family relatives have a 50 percent chance of develop AD because the tendency is hereditary as an autosomal predominant allele trait . In some familial AD cases , an abnormal gene berth has been located on chromosome 21 . Other genetic or environmental factors are apt(predicate) to be discovered in the futureUntil the cause of AD is unconquerable , a be restored of AD is determined , a cure forget remain rugged . There are no treatments that call on the tier of illness . near authoritative experimental in AD , or that retard the course of illness . Most catamenia experimental drug trials have sought to objurgate the take flight in acetylcholine neurotransmission . To date , such medicines have proven futile , but developing drugs to place other biochemical abnormalities sight in the brain of patients with AD may further to expedient treatmentsThe intents of this are to (1 ) understand what Alzheimer s disease really is (2 ) stick out out the warning signs of Alzheimer s disease and (3 ) be aware of the threesome types of dementiaII .
