19 Possible Causes for EEG Periodic Patterns, Encephalomalacia, Headache

  • Stroke

    In contrast, DWI remains elevated due to persistent high T2/FLAIR signal ( T2 shine through ), unless hemorrhage ( T2 blackout ) or cystic encephalomalacia 10.[radiopaedia.org] RESULTS: We report on two patients who presented with headache and mild hypertension after 4-FA use.[ncbi.nlm.nih.gov] Andraus ME, Andraus CF, Alves-Leon SV (2012) Periodic EEG patterns: importance of their recognition and clinical significance.

  • Subarachnoid Hemorrhage

    The headache preceding an intracranial aneurysm rupture is called a sentinel headache (SH), and it is characterized by a sudden, intense, and persistent headache.[ncbi.nlm.nih.gov] In Part 1 of this episode on Headache Pearls & Pitfalls – Migraine Headache & Subarachnoid Hemorrhage, Dr. Anil Chopra and Dr.[emergencymedicinecases.com] […] in the emergency department on EM Cases: Episode 14 Part 2: Thunderclap Headache – Cerebral Venous Thrombosis and Cervical Artery Dissection Best Case Ever 3: Emergency Headache[emergencymedicinecases.com]

  • Encephalitis

    Eventually, it results in marked cystic encephalomalacia and volume loss in affected areas.[radiopaedia.org] Over-the-counter medications may be used for fever and headache. Individuals with encephalitis or bacterial meningitis are usually hospitalized for treatment.[web.archive.org] Other symptoms include: sudden fever, headache, vomiting, heightened sensitivity to light, stiff neck and back, confusion and impaired judgment, drowsiness, weak muscles,[ninds.nih.gov]

  • Traumatic Brain Injury

    Chronic extra-axial fluid collections, cerebral atrophy, and cystic encephalomalacia are common late sequelae. 29 Sequential cranial imaging studies are recommended.[doi.org] […] psychotherapy was beneficial in de-sensitizing many post-traumatic memories, and in managing post-concussion pain, including neuropathic pain and post-traumatic migraine headaches[ncbi.nlm.nih.gov] Cases are used to demonstrate the commonly encountered pathologies of headache, cognitive issues, and mood disturbances following injury.[ncbi.nlm.nih.gov]

  • Herpes Zoster Encephalitis

    Eventually, it results in marked cystic encephalomalacia and volume loss in affected areas.[radiopaedia.org] Typical symptoms such as a headache, vomiting, fever and altered consciousness appear, with or without the onset of typical rash.[symptoma.com] [Periodical EEG pattern modifications in herpetic encephalitis treated with acyclovir]. Rev Neurol. 1996 Jul. 24(131):829-32. [Medline].[emedicine.medscape.com]

  • Multiple Sclerosis

    The new onset of hypertension or headache requires careful attention in cases of long-term administration of IFN-β1b.[ncbi.nlm.nih.gov] She had no symptoms other than occasional, mild headaches and had no findings to suggest clinically isolated syndrome (CIS) or MS; additionally, her cerebrospinal fluid analysis[ncbi.nlm.nih.gov] Adverse events with ibudilast included gastrointestinal symptoms, headache, and depression.[ncbi.nlm.nih.gov]

  • Citrullinemia

    The neonates with hyperammonemic encephalopathy had extensive brain injuries at the onset of hyperammonemia, followed by encephalomalacia and brain atrophy at quite an early[ncbi.nlm.nih.gov] Onset may also occur in adults, where the disease is characterized by periods of hyperammonemia, reduced alertness, headache or migraine.[sema4genomics.com] EEG was pathologic in two cases, in one case generalized burst suppression pattern, and in the other mild epileptiform disorder originating from the centrotemporal regions[jpedres.org]

  • Status Epilepticus
