Alzheimer's Disease

Alzheimer's disease (AD), also called Alzheimer diseasesenile dementia of the Alzheimer type (SDAT), primary degenerative dementia of the Alzheimer's type(PDDAT), or simply Alzheimer's, is the most common form of dementia. This incurable, degenerative, and terminal disease was first described by German psychiatrist and neuropathologist Alois Alzheimer in 1906 and was named after him. Most often, it is diagnosed in people over 65 years of age, although the less-prevalent early-onset Alzheimer'scan occur much earlier. In 2006, there were 26.6 million sufferers worldwide. Alzheimer's is predicted to affect 1 in 85 people globally by 2050.

Although the course of Alzheimer's disease is unique for every individual, there are many common symptoms. The earliest observable symptoms are often mistakenly thought to be 'age-related' concerns, or manifestations of stress. In the early stages, the most commonly recognised symptom is inability to acquire new memories, such as difficulty in recalling recently observed facts. When AD is suspected, the diagnosis is usually confirmed with behavioural assessments and cognitive tests, often followed by a brain scan if available.

As the disease advances, symptoms include confusion, irritability and aggression, mood swings, language breakdown, long-term memory loss, and the general withdrawal of the sufferer as their senses decline. Gradually, bodily functions are lost, ultimately leading to death. Individual prognosis is difficult to assess, as the duration of the disease varies. AD develops for an indeterminate period of time before becoming fully apparent, and it can progress undiagnosed for years. The mean life expectancy following diagnosis is approximately seven years.Fewer than three percent of individuals live more than fourteen years after diagnosis. 


Spinal Fluid Marker May Identify Alzheimer's Disease Earlier

Researchers have found levels of specific components of the cerebrospinal fluid were reduced in patients with mild cognitive impairment who later developed Alzheimer disease, compared with others patients with MCI who did not develop Alzheimer's.

Dementia Risk Decreases With Moderate Alcohol Drinking

Go ahead and drink that glass of wine, as new research shows that moderate social drinking reduces the risk of dementia and cognitive impairment. Researchers at Loyola University Chicago Stritch School of Medicine conducted an analysis of 143 studies and found that moderate drinkers were 23 percent less likely to develop cognitive impairment, Alzheimer's disease and other forms of dementia, a press release from the school stated.
