Frontotemporal dementia (FTD), a common cause of dementia, is a group of disorders that occur when nerve cells in the frontal and temporal lobes of the brain are lost. This causes the lobes to shrink. FTD can affect behavior, personality, language, and movement.
These disorders are among the most common dementias that strike at younger ages. Symptoms typically start between the ages of 40 and 65, but FTD can strike young adults and those who are older. FTD affects men and women equally.
The most common types of FTD are:
A less common form of FTD affects movement, causing symptoms similar to Parkinson disease or amyotrophic lateral sclerosis (Lou Gehrig’s disease).
The cause of FTD is unknown. Researchers have linked certain subtypes of FTD to mutations on several genes. Some people with FTD have tiny structures, called Pick bodies, in their brain cells. Pick bodies contain an abnormal amount or type of protein.
A family history of FTD is the only known risk for these diseases. Although experts believe that some cases of FTD are inherited, the majority of people with FTD have no family history of it or other types of dementia.
Symptoms of FTD start gradually and progress steadily, and in some cases, rapidly. They vary from person to person, depending on the areas of the brain involved. These are common symptoms:
Some people have physical symptoms, such as tremors, muscle spasms or weakness, rigidity, poor coordination and/or balance, or difficulty swallowing. Psychiatric symptoms, such as hallucinations or delusions, also may occur, although these are not as common as behavioral and language changes.
Family members are often the first to notice subtle changes in behavior or language skills. It’s important to see a health care provider as early as possible to discuss:
No single test can diagnose FTD. Typically, health care providers will order routine blood tests and perform physical exams to rule out other conditions that cause similar symptoms. If they suspect dementia, they may:
Currently, no treatments are available to cure or slow the progression of FTD, but health care providers may prescribe medications to treat symptoms. Antidepressant medications may help treat anxiety and control obsessive-compulsive behaviors and other symptoms. Prescription sleeping medications can help ease insomnia and other sleep disturbances. Antipsychotic medications may reduce irrational and compulsive behaviors.
Behavior modification may help control unacceptable or risky behaviors.
Speech and language pathologists and physical and occupational therapists can help adjustment to some of the changes caused by FTD.
FTD is not life-threatening ─ people may live with it for years. But it can lead to an increased risk for other illnesses that can be more serious. Pneumonia is the most common cause of death, with FTD. People are also at increased risk for infections and fall-related injuries.
As FTD progressively worsens, people may engage in dangerous behaviors or be unable to care for themselves. They may need 24-hour nursing care or to stay in an assisted living facility or nursing home.
Coping with FTD can be frightening, frustrating, and embarrassing for the patient and family members. Since some symptoms can’t be controlled, family members shouldn't take their loved one’s behaviors personally. Families need to maintain their own well-being, while ensuring that their loved one is treated with dignity and respect.
Caregivers should learn all they can about FTD and assemble a team of experts to help the family meet the medical, financial, and emotional challenges they are facing.
It’s important to find a health care provider knowledgeable about FTD. Other health care specialists who may play a role on the team are home care nurses, neuropsychologists, genetic counselors, speech and language therapists, as well as physical and occupational therapists. Social workers can help the patient and caregivers find community resources, such as medical supplies and equipment, nursing care, support groups, respite care, and financial assistance.
Attorneys and financial advisors can help families prepare for the later stages of the disease.
Advanced planning will help smooth future transitions for the patient and family members, and may allow all to participate in the decision-making process.
Little solid evidence exists that antioxidants and other supplements help those with FTD. You and your family members should talk with your health care provider about whether you should take antioxidants and other supplements, such as coenzyme Q10, vitamin E, vitamin C, and B vitamins to support brain health.
If you are diagnosed with FTD, you and your caregivers should talk with your health care providers about when to call them. Your health care provides will likely advise calling if your symptoms become worse, or if you have obvious and/or sudden changes in behavior, personality, or speech. This includes mood changes, such as increasing depression or feeling suicidal.
