18 Possible Causes for Rhythmic Slowing Temporal Left, Slowing - Delta Waves Unilaterally, Slowing - Theta Waves Unilaterally on the Right

  • Stroke

    Thalamic lesions generally produced focal or unilateral delta activity, but the slow activity varied in time of onset, amplitude and degree of focality 16.[scielo.br] Bilateral hypothalamic and bilateral mesencephalic lesions produced bilateral slow waves 16.[scielo.br]

  • Brain Concussion

    A brain concussion is a still incompletely defined syndrome of traumatic brain injury (TBI) that causes a spectrum of symptoms without evident structural damage to the brain. A headache, cognitive deficits, emotional instability, sleep disturbances, and an overall change in mental state after trauma are highly[…][symptoma.com]

  • Traumatic Brain Injury

    This case report reveals the implementation of sensorimotor adaptation and learning process for rehabilitation in a patient with traumatic brain injury to achieve optimum recovery which is permanent in nature in compliance to the disability rating scale. A twenty two year old gentleman who had a history of fall was[…][ncbi.nlm.nih.gov]

  • Migraine

    A migraine is a primary headache disorder characterized by recurrent headaches that are moderate to severe. Typically, the headaches affect one half of the head, are pulsating in nature, and last from two to 72 hours. Associated symptoms may include nausea, vomiting, and sensitivity to light, sound, or smell. The[…][en.wikipedia.org]

  • Epilepsy

    The clinical presentation of patients with epileptic encephalopathies can be heterogenous. When attempting to classify a patient's epilepsy syndrome, challenges can arise due to the phenotypic overlap of various epilepsies as well as the different presentations of mutations within the same gene. Genetic testing can[…][ncbi.nlm.nih.gov]

  • Meningoencephalitis

    […] or bilateral slowing in the delta or theta frequencies and focal sharp-wave activity. 14 Pathological findings of von Economo disease typically consist of a nonhemorrhagic[jamanetwork.com] The CSF glucose level is invariably normal, but oligoclonal band positivity has been reported. 21 An EEG during the acute phase of the illness often shows diffuse unilateral[jamanetwork.com]

  • Cerebral Hemorrhage

    Intracerebral hemorrhage is a rare event during pregnancy that can result in serious morbidity and mortality for the mother and infant. In this article, we describe a case involving a multiparous woman at 34 weeks gestation who presented with a 5-cm intracerebral bleed. Within 2 hours of presenting, she underwent[…][ncbi.nlm.nih.gov]

  • Astrocytoma

    A 41-year-old man presented to us with left arm and leg weakness and mild word finding difficulties. His preoperative magnetic resonance imaging (MRI) demonstrated abnormal T1 and T2 signal changes in the right temporal lobe and basal ganglia, indicative of possible glioma. An awake craniotomy for right temporal[…][ncbi.nlm.nih.gov]

  • Meningioma

    Meningioma, also known as meningeal tumor, is typically a slow-growing tumor that forms from the meninges, the membranous layers surrounding the brain and spinal cord. Symptoms depend on the location and occur as a result of the tumor pressing on nearby tissue. Many cases never produce symptoms. Occasionally[…][en.wikipedia.org]
