When mental ability declines severely enough to interfere with daily life, it is labeled as dementia. At least two brain functions such as memory loss, reasoning, and communication will be impaired. Frontal lobe dementia, sometimes referred to as frontotemporal dementia affects the temporal and frontal lobes of the brain. Portions of these lobes actually atrophy or shrink. These areas are associated with the functions of personality, behavior, and language. The signs and symptoms of frontal lobe dementia will depend on the exact portion of the brain affected.
Information. Because the signs and symptoms of frontal lobe dementia vary greatly among individuals, it is sometimes misdiagnosed as a psychiatric problem or Alzheimer’s disease. Some symptoms do overlap with those of Alzheimer’s. However, the disorder appears in much younger patients, generally between ages 40 to 65 while most cases of Alzheimer’s are seen in those 65 and older. Frontal lobe dementia is estimated to be responsible for between 10 and 15 percent of all dementia cases. The disorder progresses over time to the point where the patient will require 24-hour care. Research has identified clusters of symptoms that appear to occur together. More than one cluster may be present in the same person.
