Unprovoked Seizures in Autistic Individuals
Seizure (Sudden, Abnormal electrical activity in brain)
Partial seizure (Focal, sensory or petit mal)(one part of brain; particularly the site which directs “flight” response; conscious; either tonic or clonic)
Generalized seizure
(Both site of brain)
Unconscious; Both tonic and clonic
Simple
(No loss of consciousness)Complex
Epilepsy – a recurrent seizure
Non-epileptic Seizure – Similar to epileptic.
Seizure but not caused by electrical disruption of cerebral cortex. Classified as 1) physiologic or 2) psychogenic

Age Group
4 -16 years ; N = 89 (Boys - 66, Girls – 23)
Repetitive Epileptic Seizure

Epileptic Seizure was confirmed by EEG on29 boys and 5 girls
17 children had spinal tap for unrelated reason

Autism, Seizure & Neurotransmitters Autism, Seizure & Neurotransmitters (NT)(NT)
NTs are chemicals that transfer information from one neuron to another
NTs have two basic functions
• Inform receiving neuron to “Fire” Excitatory
• Inform receiving neuron to stop “Firing” Inhibitory
These actions of NTs depend on a class of proteins which is known as receptors.
These receptors initiate the activity after receiving the NTs.
GABA, for example, binds to receptors which are inhibitory.
Most anti anxiety medications increase GABA transmission More GABA receptor activation Shut down the CNS Relaxation
GABA Receptor
GABAergic system in cerebellum and limbic structure in affected in autism. Inhibition of this system is suppressed by
1. Impairment of GABA-receptor
2. Antagonism of GABAergic neurons bearing receptors sensitive to glutamate analog NMDA.
Example:
Pathology relating to GABA receptors and suspected etiologies of autism
Excessive glutamate activation of non-NMDA glutamate receptor – Pathology observed in Autism

Controlling Seizures by Nutritional ApproachControlling Seizures by Nutritional ApproachKetogenic Diet : A diet high in fats, low in protein and carbohydrate.
Fat: (carb + protein) = 4:1
However, never make too low carb (Hypoglycemia) Medium chain Triglycerides (MCT) are more ketogenic.
