18 Possible Causes for Arrhythmic Slowing Occipital Right, Slowing - Delta Waves Unilaterally

  • 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

    Traumatic brain injury (TBI) is a major health and socioeconomic problem that affects all societies. In recent years, patterns of injury have been changing, with more injuries, particularly contusions, occurring in older patients. Blast injuries have been identified as a novel entity with specific characteristics.[…][ncbi.nlm.nih.gov]

    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]

  • Astrocytoma

    Infants with low-grade glioma (LGG) and diencephalic syndrome have a poor outcome. The patient described here had a desmoplastic infantile astrocytoma harboring a BRAF V600E mutation. After relapse following initial standard chemotherapy treatment, he was successfully treated with the BRAF V600E inhibitor[…][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]
