10 Possible Causes for EEG Generalized Slowing, Episodic Blurred Vision, Syncope

  • Hypoglycemia

    vision Headache Trouble performing routine tasks Note: Symptoms can vary from person to person and episode to episode.[] A 64 year-old African female was brought to the emergency room with a 1-month history of recurrent syncope, weight loss, and abdominal bloating.[] The symptoms include being: Hungry Shaky Sleepy Anxious Dizzy Confused or nervous Sweaty Irritable Syncope (Passing out, losing consciousness) Some people have trouble speaking[]

  • Stroke

    He developed headache, nausea, vomiting, blurred vision, diplopia, dizziness, and ataxia following the procedure.[] The largest proportions of chameleons were AMS, syncope, hypertensive emergency, systemic infection, and suspected ACS.[] CONCLUSIONS: Abnormal EEG in general and generalized slowing in particular are associated with clinical deterioration after acute ischemic stroke.[]

  • Temporal Lobe Epilepsy

    Advanced neurophysiologic techniques such as EEG and magnetoencephalography source imaging can help to determine the area generating the initial and propagated interictal[] ; recurrent nightmares of stereotyped kind episodes of blurred vision or diplopia Not Necessarily Disintegrative PTLSs (NPTLSs) Symptoms Not Necessarily Requiring Treatment[] We report a case of a previously healthy man presenting with syncope in whom telemetry revealed sinus arrest.[]

  • Migrainous Stroke

    Electroencephalograms (EEGs) were performed in five patients and showed generalized slowing.[] Furthermore, she continued to have dizziness and occasional episodes of blurred vision and vomiting.[] However, this migraine variant may also cause ringing in the ears, slurred speech, loss of balance, syncope, and even loss of consciousness prior to a headache.[]

  • Familial Dysautonomia

    Non-epileptiform EEG findings including generalized or focal slowing or generalized or focal cerebral dysfunction, were present in 74 (18.5 %) patients.[] They may experience a sharp drop in blood pressure upon standing ( orthostatic hypotension ), which can cause dizziness, blurred vision, or fainting.[] We questioned why despite low blood pressure standing, surprisingly few familial dysautonomia patients complain of symptomatic hypotension or have syncope.[]

  • Migraine Headache Equivalent

    Collateral symptoms other than headaches accompanying vertigo attacks were pallor, nausea, vomiting, phonophobia, photophobia and blurring of vision.[] The differential diagnosis includes various causes of syncopal, inner-ear, intoxication, and posterior-fossa pathologies. [47] However, the yield for diagnostic testing is[] […] sensitivity, mood change, irritability, personality change, confusion, anxiety, blurred vision, distress, stuffy nose, and a fever that may run as high as 104 F.[]

  • Episodic Ataxia

    Fig. 2 EEG of case III2 during complex partial epileptic seizure. Right temporal sharp and slow waves generalize to involve the right hemisphere.[] During episodes, many of those affected manifest dizziness, nausea, vomiting, headaches, blurred or double vision, dyslexia and tinnitus.[] EPILEPSY IMITATORS OVERVIEW SYNCOPE AND ANOXIC SEIZURES Vasovagal syncope Reflex anoxic seizures Breath-holding attacks Hyperventilation syncope Compulsive valsalva Neurological[]

  • Acute Disseminated Encephalomyelitis

    EEG showed generalized theta slowing. Brain biopsy was performed because of concerns for lymphoma and his unresponsiveness to all standard treatments.[] […] or blurred vision), episodes of "disturbed/blackened" rather than blurry indicate moderate stage and require immediate medical attention to prevent further loss of vision[] A number of clinical syndromes, including dizziness or vertigo, limb weakness, syncope, and paresthesias, were poorly defined and unassociated with short-term morbidity and[]

  • Spastic Ataxia with Congenital Miosis

    By 13 months, EEG showed features of West syndrome, hypsarrhythmia, and generalized slowing, consistent with a diffuse encephalopathic process.[] During these episodes, many people also experience dizziness (vertigo), nausea and vomiting, migraine headaches, blurred or double vision, slurred speech, and ringing in the[] From the central nervous system: d izziness, syncope, drowsiness, headache, paresthesia, sensation of tingling, sensitivity, nervousness, confusion and/or emotional stimulation[]

  • Lethal Neonatal Spasticity - Epileptic Encephalopathy Syndrome

    Cognitive deficits Abnormal imaging in 2/3, cryptogenic in 1/3 EEG findings: Slow generalized spike-and-wave discharges (1-2 Hz) AEDs of choice: Valproate, clonazepam, ethosuximide[] Leber hereditary optic neuropathy (blurring, loss of central vision) 2. MERRF (myoclonic epilepsy, ragged red fibers) 3.[] Similar Symptoms : See also the causes of symptoms similar to seizures, such as: Convulsions Fits Tics Twitches Muscle spasms Fainting Syncope Chorea Clonus Myoclonus Spasticity[]
