14 Possible Causes for EEG Seizure Activity, Small Hippocampi, Visual Hallucination

  • Temporal Lobe Epilepsy

    […] of seizure onset by scalp EEG.[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

    EEG can show unusual electrical activity patterns. Different types of seizures can be identified with these patterns.[cedars-sinai.edu] […] 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]

  • Focal Motor Seizure

    During a video-EEG study, these focal motor seizures progressed into a generalised myoclonic status epilepticus.[semanticscholar.org] 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]

  • Generalized Motor Seizure

    Sometimes, the visible symptoms last longer than the seizure activity on an EEG.[epilepsytalk.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] Jacksonian march (“march of convulsions”): progressive involvement of muscle groups Sensory and psychiatric symptoms Visual (e.g., hallucinations, micropsia, macropsia) Somatic[amboss.com]

  • Jacksonian Seizure

    This records electrical activity in the brain. EEG can show unusual electrical activity patterns. Different types of seizures can be identified with these patterns.[cedars-sinai.edu] 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

    In generalized seizure patients, the activation of photic stimulation and/or hyperventilation during an EEG may produce spikes or even seizures.[emedicine.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) 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

    If you have had a seizure or if you are prone to seizures, your EEG may show an area or several areas of erratic electrical brain activity.[verywellhealth.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] Virtually any movement, sensory, or emotional symptom can occur as part of a partial seizure, including complex visual or auditory hallucinations.[epilepsywisconsin.org]

  • Early Infantile Epileptic Encephalopathy Type 6

    […] onset activity, (3) seizure like activity and (4) seizure termination.[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]

  • Transient Global Amnesia

    An electroencephalogram (EEG) may also be used to look for seizure activity.[belmarrahealth.com] Regarding the small size of TGA lesions, DWI sequence performed with 3mm thickness and with higher b-values (b 2000 or 3000) may increase detection.[ajnr.org] The patient was alert, aware, and attentive, without auditory or visual hallucinations or delusions.[innovationscns.com]

  • Amnesia

    For this reason, getting an electroencephalogram (EEG) is a good idea, though a normal EEG does not exclude the possibility of subtle seizure activity too deep to be detected[verywell.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]
