- Frontotemporal dementia (FTD) is the second most common cause of early-onset dementia. Alzheimer s disease is the most common. Alzheimer s disease happens most often in the elderly, but FTD typically appears between 40 and 60 years of age. It also has a strong genetic component: Up to 40% of FTD cases are linked to positive family histories. Earlier diagnoses and genetic tests mean that people with FTD will spend more years in earlier stages of disease, aware that they have it. However, few studies have looked at the personal experiences or coping styles of people with FTD. Researchers want to interview people with FTD and their caregivers to understand their experiences with the disease. This information will help create better treatments and therapies for those affected by FTD.
