EurekAlert! -- Frontal lobe dementia (Frontotemporal Dementia, FTD) strikes people at an earlier age. After Alzheimer’s disease, FTD is the form of dementia that occurs most frequently in patients younger than 65. In FTD, the disease process starts in the frontal lobe where large numbers of brain cells begin to die off. The frontal lobe is the foremost part of the brain and constitutes about 30% of the brain. Among other things, it is involved in regulating behavior, movement and mood, and it is responsible for cognitive functions such as language. So, the first clinical signs of FTD are changes in behavior and personality, and then, in a later stage of the disease, the loss of memory functions.
