Two forms of the 6/sec spike and wave complex. 1980

J R Hughes

In 3 decades 1550 patients showed 6/sec spike and wave complexes; 839 were chosen for computer-analyzed electroclinical correlations. Control groups (each 500) included patients (1) randomly selected from EEG files, (2) with normal EEGs, (3) with only slow wave abnormalities, and (4) with only spike abnormalities. In the experimental group more females and Caucasians were found with peak age distribution at 11--15 years. The major symptoms were seizures (53%), neurovegetative (51%) and psychological complaints (24%), all significantly different from control groups, except for seizures in control group 4. Seizures were mainly generalized motor attacks, neurovegetative symptoms included headaches, dizziness and blackouts and psychological symptoms were mainly behavior disorders. As a presumed etiology head injury was noted in over 25% with this complex, which was maximal either on the anterior or occipital areas. Further computer analysis shows that two extreme forms can be identified: (1) the WHAM form, seen mainly in waking records, high amplitude, anterior location, more males, and (2) the FOLD form, seen mainly in females, occipital location, low amplitude, in drowsy states. The WHAM form appears primarily in patients with seizures, and the FOLD form in patients with neurovegetative and psychological complaints.

D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D001924	Brain Concussion	A nonspecific term used to describe transient alterations or loss of consciousness following closed head injuries. The duration of UNCONSCIOUSNESS generally lasts a few seconds, but may persist for several hours. Concussions may be classified as mild, intermediate, and severe. Prolonged periods of unconsciousness (often defined as greater than 6 hours in duration) may be referred to as post-traumatic coma (COMA, POST-HEAD INJURY).

D001927	Brain Diseases	Pathologic conditions affecting the BRAIN, which is composed of the intracranial components of the CENTRAL NERVOUS SYSTEM. This includes (but is not limited to) the CEREBRAL CORTEX; intracranial white matter; BASAL GANGLIA; THALAMUS; HYPOTHALAMUS; BRAIN STEM; and CEREBELLUM.

D001930	Brain Injuries	Acute and chronic (see also BRAIN INJURIES, CHRONIC) injuries to the brain, including the cerebral hemispheres, CEREBELLUM, and BRAIN STEM. Clinical manifestations depend on the nature of injury. Diffuse trauma to the brain is frequently associated with DIFFUSE AXONAL INJURY or COMA, POST-TRAUMATIC. Localized injuries may be associated with NEUROBEHAVIORAL MANIFESTATIONS; HEMIPARESIS, or other focal neurologic deficits.

D002540	Cerebral Cortex	The thin layer of GRAY MATTER on the surface of the CEREBRAL HEMISPHERES that develops from the TELENCEPHALON and folds into gyri and sulci. It reaches its highest development in humans and is responsible for intellectual faculties and higher mental functions.

D004834	Epilepsy, Post-Traumatic	Recurrent seizures causally related to CRANIOCEREBRAL TRAUMA. Seizure onset may be immediate but is typically delayed for several days after the injury and may not occur for up to two years. The majority of seizures have a focal onset that correlates clinically with the site of brain injury. Cerebral cortex injuries caused by a penetrating foreign object (CRANIOCEREBRAL TRAUMA, PENETRATING) are more likely than closed head injuries (HEAD INJURIES, CLOSED) to be associated with epilepsy. Concussive convulsions are nonepileptic phenomena that occur immediately after head injury and are characterized by tonic and clonic movements.
