| epilate | To extract a hair; to remove the hair from a part by forcible extraction, electrolysis, or loosening at the root by chemical means. Compare: depilate. Origin: L. E, out, + pilus, a hair (05 Mar 2000) |
| epilation | The act or result of removing hair. Synonym: depilation. (05 Mar 2000) |
| epilatory | 1. Having the property of removing hair; relating to epilation. Synonym: depilatory, psilotic. See: decalvant. Synonym: depilatory. (05 Mar 2000) |
| epilemma | The connective tissue sheath of nerve fibres near their termination. Origin: epi-lemma, husk (05 Mar 2000) |
| epilemmal ending | A nerve ending in close relation to the outer surface of the sarcolemma. (05 Mar 2000) |
| epilepidoma | <tumour> A tumour resulting from hyperplasia of tissue derived from the true epiblast. Origin: epi-+ G. Lepis, rind, + -oma, tumour (05 Mar 2000) |
| epilepsia | <disease, neurology> The paroxysmal transient disturbances of brain function that may be manifested as episodic impairment or loss of consciousness, abnormal motor phenomena, psychic or sensory disturbances or perturbation of the autonomic nervous system. Symptoms are due to paroxysmal disturbance of the electrical activity of the brain. On the basis of origin, epilepsy is idiopathic (cryptogenic, essential, genetic) or symptomatic (acquired, organic). On the basis of clinical and electroencephalographic phenomenon, four subdivisions are recognised: 1. Grand mal epilepsy (major epilepsy, haut mal epilepsy) subgroups: generalised, focal (localised), jacksonian (rolandic) 2. Petit mal epilepsy 3. Psychomotor epilepsy (temporal lobe epilepsy, psychic, psychic equivalent or variant) subgroups: psychomotor proper (tonic with adversive or torsion movements or masticatory phenomena), automatic (with amnesia) and sensory (hallucinations or dream states or d굁. Vu) 4. Autonomic epilepsy (diencephalic), with flushing, pallor, tachycardia, hypertension, perspiration or other visceral symptoms. Synonym: epilepsia. Origin: Gr. Epilepsia = seizure (14 May 1997) |
| epilepsia partialis continua | Focal motor status epilepticus characterised by high fever, delirium, localised muscular spasms and generalised convulsion, then clonic twitching of one group of muscles at regular intervals (seconds apart) lasting for hours or months, remaining localised. These continue throughout sleep, possibly at a reduced rate. (12 Dec 1998) |

| epilepsy with grand mal seizures on awakening | Generalised epilepsy syndrome characterised by onset in the second decade of life, typically with generalised tonic-clonic seizures, of which most occur shortly after awakening (regardless of the time of day) and are exacerbated by sleep deprivation. There is a genetic predisposition and EEG shows one of several generalised patterns of interictal discharges; photosensitivity is common. (05 Mar 2000) |
| epilepsy with myoclonic absences | A form of generalised epilepsy characterised by absence seizures, severe bilateral rhythmic clonic jerks often associated with tonic contraction, and an EEG 3 Hz spike and wave pattern. Age of onset is usually around seven years and males are more often affected. (05 Mar 2000) |
| epilepsy, absence | Epileptic seizures that consist of a sudden cessation of ongoing conscious activity without convulsive muscular activity or loss of postural control. These seizures may be so brief as to be inapparent, lasting seconds and occasionally several minutes. Absence seizures usually begin in otherwise neurologically normal children and rarely appear for the first time in adults. The seizures may occur hundreds of times per day and go on for weeks or months before it is recognised that a child is having seizures. (12 Dec 1998) |
| epilepsy, complex partial | Epileptic seizures that are episodic changes in behaviour in which an individual loses conscious contact with the environment. The onset of such seizures involves any of a variety of auras: deja-vu, an unusual smell, a sudden intense emotional feeling, a sensory illusion such as micropsia (objects growing smaller) or macropsia (objects growing larger), or other sensory hallucination. There may be a cessation of activity with some minor motor activity such as lip smacking, walking aimlessly, or other automatisms. The seizures may also be accompanied by the unconscious performance of highly skilled activities such as driving a car. When the seizure ends, the individual is amnesic for events that took place during the seizure and may take minutes or hours to recover fully to consciousness. (12 Dec 1998) |
| epilepsy, frontal lobe | Epileptic seizures arising from the frontal lobe characterised by simple partial, complex partial, secondary generalised seizures, or combinations of these. The seizures, which are short in duration, may occur several times a day, mostly during sleep. Affected individuals usually have prominent motor manifestations which are tonic or postural, complex gestational automatisms at the onset, and fall to the ground when the discharge is bilateral. Status epilepticus is a frequent complication. (12 Dec 1998) |
