Were you looking for information about Dementia? Demencha is a common misspelling of dementia.
Although dementia is common in very elderly individuals, it is not a normal part of the aging process. People with dementia may have memory problems, experience behavioral problems or personality changes, and lose their ability to maintain emotional control and solve problems. This is caused by Alzheimer's disease in most cases, but other possible causes include multi-infarct dementia, Creutzfeldt-Jakob disease, and Huntington's disease. Most symptoms cannot be stopped or reversed, but about 10 percent of dementia causes are treatable conditions.
