Symptoms of frontotemporal, or frontal lobe, dementia fall into three dominant symptom clusters: behavioral changes, speech and language changes, and movement disorders, states Mayo Clinic. Under behavioral changes, symptoms include apathy, loss of empathy, a deteriorating in personal hygiene and overeating. Symptoms of speech and language changes include primary progressive aphasia, semantic dementia and logopenic phonological aphasia, while movement disorders include tremors, muscle weakness and rigidity. Symptoms vary from individual to individual.
Frontotemporal dementia is a condition where progressive damage to the brain's temporal and frontal lobes causes different types of brain disorders, explains the Association for Frontotemporal Degeneration. The disease usually starts when a person is in his 50s or 60s, although it may also affect people as young as those in their 20s. Although the condition is not life threatening, it causes a progressive decline in a person's function, behavior and language such that he finds it difficult to interact with others, take care of himself, and even plan or organize things. As of 2015, there is no treatment for the condition, and this decline may last from two to 20 years and much longer from the disease onset. Other names for frontotemporal dementia include frontotemporal degeneration and Pick's disease.
