Subcortical dementia

What is Subcortical dementia?

Dementia, also known as Senility, is a broad category of brain diseases that cause a long term and often gradual decrease in the ability to think and remember such that a person's daily functioning is affected. Other common symptoms include emotional problems, problems with language, and a decrease in motivation. For the diagnosis to be present it must be a change from a person's usual mental functioning and a greater decline than one would expect due to aging.

The most common type of dementia is Alzheimer's disease which makes up 50% to 70% of cases. Other common types include vascular dementia (25%), Lewy body dementia (15%), and frontotemporal dementia. Less common causes include normal pressure hydrocephalus, Parkinson's disease, syphilis, and Creutzfeldt–Jakob disease among others. A small proportion of cases run in families. In the DSM-5, dementia was reclassified as a neurocognitive disorder, with various degrees of severity. Efforts to prevent dementia include trying to decrease risk factors such as high blood pressure, smoking, diabetes and obesity. Screening the general population for the disease is not recommended.

There is no cure for dementia. Cholinesterase inhibitors such as donepezil are often used and may be beneficial in mild to moderate disease. Cognitive and behavioral interventions may be appropriate. Educating and providing emotional support to the caregiver is important. Exercise programs are beneficial with respect to activities of daily living and potentially improve outcomes. Treatment of behavioral problems or psychosis due to dementia with antipsychotics is common but not usually recommended due to there often being little benefit and an increased risk of death.

Globally, dementia affects 36 million people. For people of a specific age, however, it may be becoming less frequent, at least in the developed world, due to a decrease in risk factors. It is one of the most common causes of disability among the old. It is believed to result in economic costs of 604 billion USD a year. People with dementia are often physically or chemically restrained to a greater degree than necessary, raising issues of human rights. Social stigma against those affected is common.
