What is frontal lobe atrophy?

Frontal lobe atrophy is a reduction in the size of the frontal lobe, the most important area of ​​the brain. This part of the brain is responsible for several very important processes, and as a result, changes in its shape and structure can cause a variety of problems. Patients with frontal lobe atrophy may experience it as a stand-alone problem or in association with underlying disease. Many neurodegenerative diseases such as Huntington's are associated with shrinkage in the frontal lobe over time.

Patients with this neurological condition can develop problems with planning, emotional regulation, movement, and critical thinking. Sometimes the condition starts slowly. Symptoms are sometimes mistaken for signs of mental illness before more progressive symptoms indicative of neurological problems develop. For example, a patient may have disorganized thinking, emotional outbursts, and hallucinations, leading a doctor to initially suspect a condition such as schizophrenia.

As frontal lobe atrophy progresses, the patient may begin to develop movement disorders and more obvious neurological deficits. The frontal lobe helps the body plan and execute voluntary movements. Patients with frontal lobe degeneration may move more slowly, jerk, or have difficulty with fine motor tasks. Sometimes they have a hard time moving at all. This can also affect speech and eating, as the patient may have difficulty swallowing and articulating clearly.

A medical imaging study may show signs of frontal lobe atrophy, especially when it is extreme. Detailed, full-color images of the brain can help the doctor identify specific areas of shrinkage. These can provide information about the patient's symptoms and what the patient can expect. Medical tests can also provide information as to why the frontal lobe is shrinking. The damage is irreversible, but patients may benefit from therapy and other options to help them maintain function for as long as possible.

Researchers are sometimes interested in patients with frontal lobe atrophy because the gradual collapse of function may be related to specific areas of the brain. This can help researchers identify the areas of the brain responsible for different activities, which in turn can help with the treatment of patients with neurological disorders. Research participants are sometimes compensated for their attendance and also have access to a variety of treatment options that are free if associated with the research. A neurologist can provide more information about open clinical trials and whether a patient is eligible to participate in a trial.
