Dementia causes and symptoms
Dementia is a general term for a number of related brain issues that impact patients by causing confusion and making it hard to remember, communicate, form complete thoughts or otherwise reason.
Although dementia can be caused by many different conditions, Alzheimer's disease is the most common.
Dementia often starts with mild impacts on memory, reasoning, language skills and personality that get worse as nerve cells in the brain are damaged and parts of the brain begin to shrink.
It is most common in the elderly.
