Simple Partials:
Symptoms may be motor, sensory, psychic (states of consciousness), and/or autonomic (involuntary activity controlled by the autonomic nervous system). There is no impairment of consciousness in simple partial seizures.
Motor signs include the following:
* alternating contraction and relaxation of muscle groups
* eye movements and turning of the head to the same side
* asymmetrical posturing of the limbs
* speech arrest, vocalization
Sensory symptoms include the following:
* seeing flashes of lights or colors, illusions and hallucinations
* hearing humming, buzzing, hissing noises
* experiencing unpleasant odors and tastes
* dizziness, lightheadedness
Autonomic signs and symptoms include the following:
* borborygmi (rumbling noises produced by gas in the intestines)
* flushing
* incontinence
* nausea, vomiting
* piloerection (goose bumps)
* pupillary dilation
* sweating
* tachycardia (rapid heart rate)
Psychic symptoms include the following:
* detachment, depersonalization
* dreamy state
* memory distortion: flashback, deja vu (feeling that one has seen something before), deja entendu (feeling that one has heard something before), jamais vu (feeling that one has never seen something that is familiar), jamais entendu (feeling that one has never heard something that is familiar), panoramic vision (rapid recall of past events)
* time distortion
* unprovoked emotion: fear, pleasure, displeasure, depression, anger, elation, eroticism
Complex Partials:
Loss of consciousness distinguishes complex partial seizures from simple partial seizures. While unconscious, the patient may have "vacant" or "frightened" look and may have signs and symptoms of a simple partial seizure. Automatisms may occur during unconsciousness.
There are five types of automatisms:
* Alimentary: chewing, increased salivation, borborygmi (rumbling noises caused by gas in the intestines)
* Mimetic: facial expressions of fear, bewilderment, discomfort, tranquility, laughter, crying
* Gestural: repetitive movements of the hands, fingers, sexual gestures
* Ambulatory: wandering, running
* Verbal: repeated short phrases or swearing
Patients who have had complex partial seizures over a period of years may develop drop attacks. When this occurs, they lose postural tone and fall with the sudden onset of unconsciousness.
Complications—Complex partial seizures are easily triggered by emotional stress. The limbic structures (i.e., hypothalamus, hippocampus, amygdala) of the brain may be damaged by seizure activity. The limbic system is concerned with emotion and motivation.
These patients may develop cognitive and behavioral difficulties, such as the following:
* Interictal personality: humorlessness, dependence, obsessions, anger, hypo- or hypersexuality, emotionality
* Memory loss: short-term memory loss attributable to dysfunction in the hippocampus, anomia (inability to recall words or names of objects)
* Poriomania: prolonged aimless wandering followed by amnesia
* Violent behavior: aggression and defensiveness when subjected to restraint during a seizure
