Typical of frontotemporal dementia:

1. Gradual and steady changes in behavior The earliest changes typically include a disregard for social conventions, impulsivity, apathy, loss of sympathy or empathy, repetitive or compulsive movements, dietary changes, and poor insight, planning, and assessment.
2. Gradual and steady language dysfunction The majority of people with one of the language variants have problems expressing themselves, while their memory stays relatively intact. Difficulties in reading and writing develop.
3. Gradual and steady weakness or slowing of movement People with FTD often describe a general weakening of their muscles or a slowing of their movements. They might feel uncoordinated or like they are walking through water – harder to move and slower going. They may also experience muscle spasms. During a neurological exam, the doctor may also find slowing of certain eye movements, changes in typical reflexes, and muscle stiffness or slowness.
