Memory Praxis motor planning to perform tasks or movements In later stages of FTD, the clinical phenotypes may overlap. Recent findings from structural MRI research have indicated that eating changes in FTD are associated with atrophy wasting in the right ventral insula , striatum , and orbitofrontal cortex. Usually the first of these frontal release signs to appear is the palmomental reflex which appears relatively early in the disease course whereas the palmar grasp reflex and rooting reflex appear late in the disease course. More and more mutations and genetic variants are being identified all the time, so the lists of genetic influences require consistent updating.

What is frontotemporal dementia? Personality, emotions, behavior, and speech are controlled in these areas of the brain. These disorders cause the brain to lose brain cell function. Frontotemporal dementia is sometimes called frontal lobe dementia.
The symptoms of frontotemporal dementia depend on the areas of the brain affected. Most symptoms can be divided into one of two categories: behavior or language. Common behavioral symptoms of frontotemporal dementia include: inappropriate actions apathy, or lack of interest or enthusiasm in activities lack of inhibition or restraint neglect of personal hygiene and care compulsive behavior Common language-related symptoms of frontotemporal dementia include: difficulty speaking or understanding speech language recall problems loss of reading and writing skills difficulty with social interactions Doctors and researchers divide frontotemporal dementia into three categories.
These include: behavioral variant frontotemporal dementia: affects personality and behavior primary progressive aphasia: affects speech at first and then behavior progressive nonfluent aphasia: causes people to lose their ability to recall and speak words The type of frontotemporal dementia is determined by the most prominent symptoms.
This is known as mixed dementia. What causes frontotemporal dementia? Researchers have not identified a single cause for this type of dementia, but they have some ideas. Researchers have also identified abnormal proteins that may play a role. These proteins, found in brain cells of individuals who died with dementia, may affect how the brain works. What are the risk factors for frontotemporal dementia? Frontotemporal dementia has one known risk factor: genetics.
Scientists have found several genes related to the disease. If one of your family members is diagnosed with frontotemporal dementia, you have a greater risk.
However, not everyone with a family history will develop a problem. Instead, your doctors will try to rule out other conditions or diseases that cause similar symptoms. Some of the tests used to diagnose frontotemporal dementia include: blood tests: These can help identify other possible causes.
CT scan: A computerized tomography CT scan creates images of your brain in layers. Frontotemporal dementia cannot be cured.
Treatment is aimed at managing and alleviating symptoms. Common treatments include: Medications Some antidepressants can help reduce the behavioral problems caused by changes to the brain. Antipsychotic medications are also used to treat behavioral problems. These treatments are considered off-label drug use. However, a doctor can still use the drug for that purpose. This is because the FDA regulates the testing and approval of drugs, but not how doctors use drugs to treat their patients.
So, your doctor can prescribe a drug however they think is best for your care. Read more about off-label drug treatments. Speech therapy Speech therapy can help you learn to cope with speech difficulties. A speech therapist can also help you find alternative ways to communicate. Can lifestyle changes help frontotemporal dementia? Medication can be effective for treating dementia, but lifestyle treatments can help, too. Helping people find a comfortable environment can help them cope with the symptoms of dementia.
Environment is important. Make sure your home is well-lit and has minimal noise. People with behavior problems need to be in environments that are familiar. They may also need to avoid large crowds. People with speech problems may need to be in environments where communication is easier. They may wish to keep tools for communicating, like a pen and paper, with them all the time.
What is the outlook for frontotemporal dementia? In the early stages, the symptoms and signs of frontotemporal dementia can be cared for and treated with good results. Late-stage frontotemporal dementia can take years to develop. As the disease progresses, hour care may become necessary. The condition will eventually cause a person to have difficulty with bodily functions such as: swallowing.
