Dementia is a disorder associated with damage to brain cells. The brain has many parts, each part carrying out specific activities like thinking, movement and judgment. The hypothalamus is the cerebral part that is concerned with thinking and memory. This is the reason the first sign of dementia could be memory loss (amnesia). This part is sensitive to cell damage. When the hypothalamus is affected, cortex shrinkage occurs, giving rise to memory loss. A person suffering from dementia can remember old things but he or she cannot remember recent things.
