Alzheimer's Disease.

Alzheimers Disease Alzheimers Disease (AD) is a chronic, degenerative disease that is characterized by the bolshie of cognition. AD that occurs before the age of 60 is cognise as pre- senile dementedness. If AD occurs after the age of 60, it is know as senile dementia. AD accounts for more than 60% of both dementias (Tabers 81). AD is the ...process of cordial wasting while motor functions stick intact (Tyrer 215). Because of this psychogenic wasting, AD in late stages tends to be more rocky for the family of an AD unhurried, rather then the patient themselves. Although the cause of AD is unknown, the risk factors include family history of dementia and old age. There are three stages of AD progression. pointedness I (mild dementia) is characterized by freeing of short term remembrance and rock-bottom judgment. Stage II (moderate dementia) includes difficulty with speech and language, disposition changes, wandering, depression, paranoia and hallucinations. In St age terce (severe dementia) the patient looses the talent to execute activities of daily living and requires 24 hour care (Tabers 82). AD is diagnosed typically by eliminating other causes of dementia. In later stages of AD, an magnetic resonance imaging may show a decline in the size of it of the cortex (Treatment 4). The major pathology of AD is the depravity of cortical neurons. The enzyme acetyltransferose is decreased in the cortex.

This decrease is linked with a reduction in available acetylcholine, an important neurotransmitter (Tyrer 215). This lack of acetylcholine is dissociate of the cause of cognitive impairment. Nuerofibrillary tangles (twisted fragments of protein within nerve cells) and neuritic plaques (ab! normal clusters of dead and decease nerve cells) overly occur in patients with AD (Tabers 81). The prognosis for patients with AD is unfortunate. Patients with AD eventually loose all ability to care for themselves. wipeout normally...
