13 Possible Causes for Sleep Deprivation, Small Hippocampi, Visual Hallucination

  • Temporal Lobe Epilepsy

    PURPOSE: Sleep deprivation (SD) increases the occurrence of interictal epileptiform discharges (IED) compared to basal EEG in temporal lobe epilepsy (TLE).[ncbi.nlm.nih.gov] The control of water movement is achieved through a family of small integral membrane channel proteins called aquaporins (AQPs).[ncbi.nlm.nih.gov] 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]

  • Focal Onset Impaired Awareness Seizure

    Epileptiform discharges, when present, help localize the seizure focus A negative interictal EEG does not exclude a diagnosis of epilepsy If the waking EEG is negative, a sleep-deprived[emedicine.medscape.com] […] region of the brain, often the temporal lobes or structures found there such as the hippocampi.[en.wikipedia.org] BACKGROUND: A complex partial seizure can cause a variety of visual system signs and symptoms, including visual hallucinations, dilated pupils, and changes in vision.[ncbi.nlm.nih.gov]

  • Generalized Motor Seizure

    EEG abnormality is enhanced by sleep deprivation and in sleep. Generalized spike-and-wave often becomes fragmented with sleep deprivation or in sleep.[medlink.com] 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] hallucinations — objects or things are seen that aren’t really there Heart racing Inability to hear Inability to swallow, drooling Jamais vu (feeling that something is very[epilepsytalk.com]

  • Jacksonian Seizure

    Some triggers that can push excitability past the threshold include: Sleep deprivation Alcohol (alcohol intake AND alcohol withdrawal) Drug misuse Physical/mental exhaustion[almostadoctor.co.uk] 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] Complex visual hallucinations may occur.[epilepsydiagnosis.org]

  • Tonic-Clonic Seizure

    deprivation (2.4; 1.4-4.1), low gestational age (1.9; 1.1-3.4), mild-moderate head trauma (1.8; 1.2-3.0), and low birth weight (1.6; 1.0-2.7).[ncbi.nlm.nih.gov] 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] hallucinations (objects or things are seen that aren’t really there) Numbness, tingling, or electric shock like feeling in body, arm or leg Out of body sensations Feeling[epilepsy.com]

  • Generalized Clonic or Tonic-Clonic Seizures

    Neurological and Mental State: Normal Seizure-Precipitating Factors: Sleep deprivation, fatigue, and excessive alcohol consumption.[pennsw.com.au] 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] Virtually any movement, sensory, or emotional symptom can occur as part of a partial seizure, including complex visual or auditory hallucinations.[epilepsywisconsin.org]

  • Focal Motor Seizure

    Some patients are deprived of sleep or exposed to seizure triggers, such as rapid, deep breathing (hyperventilation) or flashing lights (photic stimulation).[encyclopedia.com] 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] More detailed visual phenomenon, called complex visual hallucinations, can also occur, either independently or with elementary visual hallucinations.[childneurologyfoundation.org]

  • Early Infantile Epileptic Encephalopathy Type 6

    Seizure precipitants were categorized as 'fever', 'visual stimuli', 'sleep deprivation', 'stress, including physical exercise', 'auditory stimuli', and 'other'.[ncbi.nlm.nih.gov] (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]

  • Amnesia

    Certain conditions, including brain diseases, head injuries, drug and alcohol intoxication, and sleep deprivation, can lead to symptoms similar to those of dissociative disorders[webmd.com] Bolouri MR, Small GA. Neuroimaging of hypoxia and cocaine-induced hippocampal stroke.[imic.or.jp] The patient and her family and friends were unaware of parkinsonism, visual hallucinations, or epilepsy for a long period.[ncbi.nlm.nih.gov]

  • Myoclonic Jerking

    After my initial visit and exam with the neuro last month, I was scheduled for a sleep study, MRI, sleep-deprived EEG and some kind of doppler study to look at the blood flow[healthboards.com] 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] Visual hallucinations and dreamlike experiences may occur but unlike epileptic seizures these are not stereotyped.[epilepsydiagnosis.org]
