10 Possible Causes for Polyspike-and-Slow-Waves, Small Hippocampi, Visual Hallucination

  • Temporal Lobe Epilepsy

    The control of water movement is achieved through a family of small integral membrane channel proteins called aquaporins (AQPs).[ncbi.nlm.nih.gov] […] complex, polyspikes, runs of rapid spikes, sharp waves, sharp-and-slow-wave complex, slow sharp waves, spikes and spike and slow waves.[jove.com] In a study published this week in Medical Humanities, the authors feel that temporal lobe epilepsy is a more likely explanation as it can produce complex visual hallucinations[medicalnewstoday.com]

  • Generalized Clonic or Tonic-Clonic Seizures

    Simple Partial Seizures Simple partial seizures only affect a small part of the brain, usually the temporal lobes or hippocampi, and are usually brief in duration, lasting[efmny.org] . • Ictal EEG consists of “Fast activity” (10 Hz or more) and slow waves, with an occasional spike-and-wave pattern. • The EEG interictal expression is of “spike-and-wave[medlink.com] Virtually any movement, sensory, or emotional symptom can occur as part of a partial seizure, including complex visual or auditory hallucinations.[epilepsywisconsin.org]

  • Myoclonic Jerking

    Simple Partial Seizures Simple partial seizures only affect a small part of the brain, usually the temporal lobes or hippocampi, and are usually brief in duration, lasting[efmny.org] Ictal EEG : The myoclonic component is associated with a generalized spike or polyspike. The atonic component is associated with the aftergoing high voltage slow wave.[medlink.com] Visual hallucinations and dreamlike experiences may occur but unlike epileptic seizures these are not stereotyped.[epilepsydiagnosis.org]

  • Jacksonian Seizure

    Simple partial seizures are seizures which affect only a small region of the brain, often the temporal lobes or structures found there such as the hippocampi.[en.wikipedia.org] EEG may detect epileptiform abnormalities (spikes, sharp waves, spike and slow-wave complexes, polyspike and slow-wave complexes).[merckmanuals.com] Complex visual hallucinations may occur.[epilepsydiagnosis.org]

  • Generalized Motor Seizure

    Simple Partial Seizures Simple partial seizures only affect a small part of the brain, usually the temporal lobes or hippocampi, and are usually brief in duration, lasting[efmny.org] Generalized spike-and-wave or polyspike-and-wave is seen in the interictal EEG. Half of the patients have these abnormalities only in sleep.

  • Early Infantile Epileptic Encephalopathy Type 6

    (E) Coronal views of the hippocampi at 2 months show bilateral small hippocampi with left hippocampal malrotation.[neurology.org] In Idiopathic Childhood Epilepsy of Gastaut seizures are brief, diurnal and frequent, consisting generally of elementary visual hallucinations and/or ictal blindness.[psiquiatriainfantil.com.br] Ictal EEG : The myoclonic component is associated with a generalized spike or polyspike. The atonic component is associated with the aftergoing high voltage slow wave.[medlink.com]

  • Atonic Seizures

    Simple Partial Seizures Simple partial seizures only affect a small part of the brain, usually the temporal lobes or hippocampi, and are usually brief in duration, lasting[efmny.org] Atonia is usually concurrent with the slow wave of a single- or polyspike-wave complex.[medlink.com] They may have visual hallucinations or may experience illusions—distortions of true sensations.[dup15q.org]

  • Focal Seizure
