Frontotemporal dementia is a type of progressive brain disorder that affects the front and temporal lobes of the brain. This condition primarily impacts a person's behavior, personality, and language abilities, leading to changes in their social interactions, decision-making skills, and communication. It is one of the most common types of dementia, with symptoms typically appearing between the ages of 45 and 65. While there is no cure for frontotemporal dementia, treatment can help manage symptoms and improve quality of life for those affected by this condition.
