15 Possible Causes for Paroxysmal Activity - Sharp-Waves, Reduced Consciousness

  • Epilepsy

    […] background, diffusemultifocal sharp waves and sharp waves-slow waves; paroxysmal fast activity Neurological examination mild diffuse hypotonia, mild ataxia with wide based[] […] discharges, diffuse (poly)spikes not available slow background, diffuse slow spike-wave discharges, sharp waves-slow waves; (poly)spike waves; paroxysmal fast activity slow[] […] hypsarrhythmia Course of EEG slow background, slow generalized spike-wave discharges and multifocal (poly)spikes slow background, left temporal slowing, slow generalized spike-wave[]

  • Encephalitis

    Clinical features included reduced consciousness, fever/hypothermia, headaches, seizures, and focal neurology.[] Some children can develop more severe symptoms over hours, days, or even weeks, including: reduced level of consciousness, hallucinations, movement/speech difficulties, behavioural[]

  • Creutzfeldt Jakob Disease

    […] level of consciousness.[] […] can look quite similar to CJD, with early lethargy and behavioural change followed by a ‘hung-up’ type of myoclonus, seizures, cognitive impairment, later motor signs and reduced[]

  • Vascular Dementia

    , i.e. reduced clarity of awareness of the environment, with reduced ability to focus, sustain, or shift attention.[] The ICD 10 diagnostic criteria for Delirium is given below ICD 10 CRITERIA FOR DELIRIUM, NOT INDUCED BY ALCOHOL AND OTHER PSYCHOACTIVE SUBSTANCES Clouding of consciousness[]

  • Panic Attacks

    For example, activating catastrophic misinterpretations increases anxiety and panic; panic attacks can be reduced as a result of cognitively challenging these misinterpretations[] Focal paroxysms of sharp wave activity appeared on both patients' EEGs coincident with the spontaneous onset of panic attack symptoms. Both patients remained conscious.[] […] to anxiety such as palpitations and sweating, are interpreted as indicating something seriously wrong such as a heart-attack, and this interpretation can be done either consciously[]

  • Encephalopathy

    Clinical features included reduced consciousness, fever/hypothermia, headaches, seizures, and focal neurology.[] […] and paroxysmal bursts of sharp and slow waves, these drugs increase epileptiform activity in known epileptic patients, clozapine increase bilateral spike waves discharges[] In the most severe form of hepatic encephalopathy, affected individuals may develop marked confusion or disorientation, amnesia, greatly dulled or reduced consciousness (stupor[]

  • Benign Familial Infantile Epilepsy Type 4

    After a prolonged unilateral clonic seizure with left-sided postictal paresis at 2 years of age, he experienced an encephalopathic state with reduced consciousness lasting[] The EEG examination showed diffuse abnormal background activity, with sporadic isolated bilateral sharp waves over the occipital regions (a).[] […] and sporadic isolated bilateral sharp waves over the occipital regions (Fig. 4a).[]

  • Benign Adult Familial Myoclonic Epilepsy

    […] brain is temporarily reduced, can mimic epilepsy.[] Alvarez and Lombroso reported hypnagogic paroxysmal spike wave activity (minimal epileptiform features, sharp waves embedded into hyperventilation , or hypnagogic hypersynchrony[] Ruling Out Other Conditions Conditions that may cause symptoms similar to epilepsy include: Syncope (fainting), a brief lapse of consciousness, in which blood flow to the[]

  • Abdominal Migraine

    Benzodiazepines - A category of potentially addictive tranquilizers that may increase depression at the same time that they reduce anxiety.[] sharp wave activity, that abdominal migraine appears to be a specific form of childhood migraine.[] These include vertigo (spinning sensations), loss of balance, and sometimes, loss of consciousness as well as prominent nausea and vomiting.[]

  • Citrullinemia

    Single-photon emission computed tomography of his brain showed reduced bilateral temporal lobar blood flow.[] […] and focal paroxysmal volleys of slow and sharp waves ( 1Hz) over the left hemisphere.[] Even if the serum citrulline level is within the normal range, citrullinemia should be considered in adult patients without primary liver dysfunction who show episodic consciousness[]
