Seven Facts About Alcohol and Dementia

Health Professional

Alcohol is thought to be a potential contributor dementia and other mental health conditions such as anxiety and depression. Here are seven interesting facts about alcohol and dementia.

1. Drinking  too much alcohol  causes damage to the cerebellum (also known as the little brain) area. The cerebellum is the structure that looks like a cauliflower at the base of the brain beneath the cerebrum. The cerebellum contains hundreds of millions of neurons that process data and relay information. It controls motor movement coordination, balance and muscle tone. Alcohol abuse over a long period of time may lead to permanent loss of coordination. It can cause blood pressure and blood cholesterol to rise damaging the blood vessels that supply blood to the brain. This can cause  vascular dementia.

2. Information as to the long-term effects of  mild to moderate alcohol intake  is less straight forward. Many scientists believe that there is no compelling evidence of an alcohol related dementia as such. Scientists point to related disorders common amongst alcoholics such as head injuries, seizures, vitamin deficiencies such as thiamine deficiency, liver damage causing hepatic encephalopathy, and smoking that can all lead to dramatic damage to the brain. The concept of  alcohol dementia  is controversial because of the difficulty of separating the role of alcohol from these other conditions that cannot be directly linked with neuropathologic findings. However there is no doubt that chronic alcohol abusers have a much increased incidence of dementia.

3. It is possible that alcohol limits the brain's  cognitive reserves  to resist diseases such as Alzheimer's.

Older people  are at risk of abusing alcohol in three key areas. Retirement, death of a spouse, and being diagnosed with a major illness can all up elders alcohol intake.
