Dementia, or senility, is characterized by a decline in cognitive abilities, personality changes, and memory loss. Alzheimer’s disease is the most common cause, but other brain disorders, medication, dehydration, and depression can also lead to it. Proper nutrition, exercise, and positive lifestyle choices can help prevent it. Some types are reversible, but most are not.
Senility, which is now more commonly referred to as dementia, is characterized by a decrease in cognitive abilities. This may include the person’s ability to concentrate, to remember information, and to judge a situation adequately. Also, the personality of someone with dementia can change and, in advanced stages, they may not be sure who they are.
There are several possible causes of senility, many of which are preventable through proper nutrition, exercise, and positive lifestyle choices. Also, some types are reversible, but this is only true in about 10% of cases.
Alzheimer’s disease is the most common cause of senility. This disease begins with difficulty learning or remembering recent events. About 3% of the population develops Alzheimer’s disease by age 65, while 20% develop it by age 85. Most people diagnosed with the condition die within ten years, with dementia steadily worsening as the disease progresses.
Over medication or dehydration can also cause a person to show signs of dementia and can lead to a false diagnosis of Alzheimer’s disease. Major depression can also cause this condition, so a person showing signs of Alzheimer’s should be tested to confirm the diagnosis.
A number of brain disorders caused by trauma, disease or infection can also lead to senility. A variety of conditions, such as Parkinson’s disease, Binswanger’s disease, Pick’s disease, Creutzfeldt-Jakob disease, Huntington’s disease, strokes, head trauma, and AIDS can also cause it. In either of these cases, the condition is generally not reversible.
Other diseases or illnesses that can cause dementia are sometimes treatable. These include hypothyroidism, pseudodementia depressive, cancers, normal pressure hydrocephalus, and deficiencies of vitamins B1, B12, and A. Individuals who abuse drugs and alcohol are also at increased risk of developing senility, as are individuals who inhale paint or other substances in to get to the top.
