Causes
The frontal lobe dementia life expectancy can be as long as seventeen years, but some patients only live two years as they soon succumb to complications of the disease. Frontal lobe dementia is distinguished from other types of dementia by the presence of abnormalities in the nerve cells of the brain — known as Pick bodies.

What are the different types of FTD?
FTD consists of three subtypes: 1 Behavioral variant FTD (bvFTDO). This is also called frontal variant FTD). This subtype accounts for about 50% of all cases of FTD. Persons with bvFTD experience progressive changes in personality, behavior, emotions, and planning and problem-solving skills. 2 Nonfluent primary progressive aphasia (PPA). This is also called agrammatic PPA). People with this subtype have difficulty forming and speaking words because the brain has trouble planning and performing the facial muscle movements needed to produce speech. They often seem to have problems with grammar, such as leaving out words or mixing up words, effortful speech, and communicate with shorter, simpler, sometimes incomplete phrases. 3 Semantic variant PPA. This is also called temporal variant FTD or semantic dementia. People with this subtype slowly lose their ability to understand the meanings of words, recognize everyday objects and familiar faces, and/or use common items.

Frontotemporal dementia (FTD) occurs when abnormal proteins (there are many kinds) build up in the brain.

Sometimes the disease is genetic, and passed down through families, but in most cases no specific cause can be found.
How to diagnose behavioral variant FTD?
Diagnosis is typically based on the clinical judgment of the doctor. Often, people with behavioral variant FTD don't believe they need to see a doctor. And when they do, they may ace the standard memory tests for dementia. Therefore, interviewing loved ones about the patients’ symptoms is often key to making the diagnosis, as patients typically cannot recognize changes in their behavior. Lab tests and brain scans will also be done to exclude other causes of impairment. Brain scans may be normal early in the course of disease. As the disease worsens, up to 65% of patients will show signs of brain damage in the frontal and temporal lobes.

FTD is not nearly as common as Alzheimer's disease, which affects an estimated 5.8 million people in the U.S., according to the Alzheimer's Association. Overall, an estimated 50,000 to 60,000 people nationwide live with FTD, says Susan L-J Dickinson, chief executive officer of the Association for Frontotemporal Degeneration. That figure may be low. "We believe that this estimate is likely an undercount, because misdiagnosis is common," Dickinson says. "Getting an accurate diagnosis of FTD depends on having access to health professionals who have experience diagnosing it. Because getting an accurate diagnosis takes 3.6 years on average, a significant number of Americans are likely never accurately diagnosed with FTD." The disorder if often misdiagnosed as a psychiatric condition, Alzheimer's or Parkinson's disease, she says. Consequently, some people with FTD are prescribed treatments for other illnesses.
Why is FTD so difficult to diagnose?
Why FTD Is Difficult to Diagnose. One of the key reasons FTD is difficult to diagnose is that there are currently no biomarkers for the disease. That means medical professionals must wait for an autopsy to make a confirmed diagnosis.
How to diagnose FTD?
There's no one clinical diagnostic test that physicians can use to diagnose FTD, says Dr. James Leverenz, a behavioral neurologist at the Cleveland Clinic. In investigating symptoms that could cause FTD, doctors typically start by ruling out other possible causes, such as stroke or a tumor, Leverenz says. An MRI can help doctors determine if there's a disproportionate amount of shrinkage in the frontal part of the brain, which could suggest FTD. Doctors can also use a PET scan to look for a pattern of reduced metabolism in the frontal or temporal parts of the brain, which could suggest FTD, he says. Other tests, like cerebrospinal fluid testing, can be useful to exclude Alzheimer's as a cause of the symptoms, Leverenz says.
