Head injury - infant

My son (who is now 3 years old) sustained a head injury when he was 11 months old, causing left frontal lobe damage, and impairing his speech.  We recently had an EEG done on him, and it came back abnormal, stating "skull defect" and "mild diffuse cerebral dysfunction".  I am writing to you for an opinion to confirm that indicates a head injury.  Also, I would like to know exactly what that means.  Does he have any chance of recovery?  What can I do to help him?

I also wanted to know - I know a head cannot cause autism, but can it cause autistic-like symptoms?

Thank you.

Frontal Lobe Damage: Generally, damage to the frontal lobes causes loss of the ability to solve problems and to plan and initiate actions, such as crossing the street or answering a complex question. But some specific impairments vary depending on which part of the frontal lobe is damaged.

If the back part of the frontal lobe (which controls voluntary movements) is damaged, weakness or paralysis can result. Because each side of the brain controls movement of the opposite side of the body, damage to the left hemisphere causes weakness on the right side of the body, and vice versa.

If the middle part is damaged, the ability to move the eyes and to perform complex movements in the correct sequence may be impaired. People may have difficulty expressing themselves in words—an impairment called Broca's (expressive) aphasia (see Brain Dysfunction: Broca's (Expressive) Aphasia).

If the front part is damaged, any of the following may result:

Impaired concentration
Reduced fluency of speech
Apathy
Inattentiveness
Delayed responses to questions
A striking lack of inhibition, including socially inappropriate behavior

People who lose their inhibitions may be inappropriately euphoric or depressed, excessively argumentative or passive, and vulgar. They may show no regard for the consequences of their behavior. They may also repeat what they say. Hope this helps you some.
