Frontotemporal Disorders?

Dementia is a loss of thinking, memory, and reasoning that affects daily activities.  It is common in older adults.  However, a group of dementias called frontotemporal disorders, or FTD, occurs most often in people between 45 and 64 years old.  So, if you start to see changes in how a loved one under 60 acts, speaks, or moves, you may not think of dementia as a cause. 
FTD sometimes runs in families and can be inherited through specific genes.  But in most cases, the cause is not known.

​People with FTD have a buildup of specific proteins in the brain cells called neurons.  It damages the cells and eventually causes them to die.  Symptoms depend on where the proteins damage the brain.  The most common symptoms of FTD are changes in behavior and personality.  However, some people with FTD may instead develop problems with speech and language, called aphasia.  FTD can also cause movement problems.
FTD can be challenging to diagnose.  Causes can include substance use or mental health disorders like depression or psychosis.  Symptoms may also tend to ebb and flow at first.  The affected may act odd, and things will appear normal for weeks or months.  Then, suddenly, symptoms get worse and become more consistent over time.
Blood tests or imaging tests like MRI or PET scans can sometimes detect specific signs of FTD.  However, some people with mild FTD can have normal findings on many tests.  If FTD is suspected, talking with a health care provider experienced with FTD can help with a diagnosis.
There is no cure for FTD, but some symptoms are manageable.  Certain antidepressant drugs can help some patients with mental health symptoms like apathy, depressed mood, or irritability.  They can also help to curb inappropriate behaviors.  Speech therapy is used for some types of aphasia, and physical therapy can help with movement problems.
The mainstay of management is education and empowerment for family members.  It includes learning ways to keep the home environment safe, manage the loved one’s behavior, and prevent caregiver burnout.
