The frontal lobe is the largest section of the brain, and damage to this area can lead to personality changes, loss of muscle control, and cognitive disturbances. Some of the specific frontal lobe lesion symptoms may involve mood swings, paralysis, or difficulty solving problems. Additional symptoms may include loss of smell, lack of muscle coordination, and memory loss.

Frontal lobe lesion symptoms associated with the area that influences personality may include unpredictable mood swings, loss of spontaneity, and difficulty controlling impulses. Abnormal social behavior and risky sexual habits may develop as a result of injury to the frontal lobe of the brain. A person with this type of injury often seems to be disinterested in people or activities that were once enjoyed.

Loss of muscle control is one of the most common frontal lobe lesion symptoms, affecting both voluntary and involuntary muscle movements. This may cause the affected person to have great difficulty performing ordinary tasks such as walking, holding a spoon, or maintaining balance. The muscles in the eyes may not function properly, leading to a variety of visual disturbances. The patient may lose the ability to control the bladder or bowels and may experience partial or complete paralysis, usually affecting one side of the body.

Cognitive dysfunction is among the possible frontal lobe lesion symptoms. Reduced performance on tests designed to measure intelligence is common, even if the affected person seems to be high-functioning. Memory loss and difficulty focusing are frequently reported when a lesion is found on this area of the brain. Patients with this type of brain injury may not be able to remember a list of two or three separate instructions and may have difficulty recalling how to perform basic tasks such as brushing the teeth or bathing.

Specific frontal lobe lesion symptoms depend on the exact location of the lesion, the extent of the damage, and the overall health of the patient. Difficulties may range from mild to completely incapacitating. It is important to remember that not everyone with damage to this part of the brain will experience the same set of symptoms or the same degree of disability. Proper medical care is vital, and a doctor should be consulted with any questions concerning individualized symptoms so that a personalized treatment plan can be developed.

I knew a lady who had a lesion on her frontal lobe. She had been a teacher and developed it before she retired. She had to take early medical retirement because of it.

Unfortunately, her lesion progressed pretty quickly and it wasn't long before she had to be admitted to a mental hospital because of her extreme mood swings. It was very, very sad because she had been a great teacher and such a nice person. No one deserves that kind of illness and it was hard watching her decline.

My sister works as a therapist in a mental hospital and said sometimes people are hospitalized there if they have frontal lobe lesions, mostly because they do affect the part of the brain that involves impulse control. If the lesion is not treatable and does not respond to medication, then a long-term care facility may be the best option for those persons who have personality and mood disorders because of the lesion.

Sometimes, she said, people can become stable on medication and can leave the hospital after a short time. But, as with any disorder involving the brain, they have to remain on their medication to keep seeing good results.
