|
Untreated PKU patients develop a broad range of symptoms related to severely impaired cognitive function, sometimes referred to as mental retardation. Other symptoms can include extreme patterns of behavior, delayed speech development, seizures, ...

Children with epilepsy may have seizures only once in a while, or every day. Though seizures can be scary for parents and caregivers, they aren't painful and are usually brief.
|
|
A seizure results from a sudden rush of abnormal electrical signals in the brain. Symptoms may range from a minor daze to uncontrollable muscle spasms (convulsion). In some cases, the victim may even lose consciousness. A seizure can be caused by a high fever, head injury, drug reaction, or condition such as epilepsy.

Although not a psychiatric disorder, epilepsy has a psychiatric aspect. The link is manifested in similar, often overlapping, symptoms, so it is important that caregivers diagnose and treat their patients with care.
|
|
People with certain mental conditions can experience seizures that appear to be epilepsy but are actually psychogenic seizures. Studies are finding ways to distinguish between the two types to facilitate proper treatment.
