14 Possible Causes for Cerebrospinal Fluid Abnormality, Frontal Intermittent Rhythmic Delta Activity, Hearing Impairment

  • Stroke

    In most cases, it occurs in a rhythmic and intermittent manner, and the most commonly and important types are frontal intermittent rhythmic delta activity (FIRDA) ( Fig 2[] Frontal intermittent rhythmic delta activity (FIRDA) in pituitary adenoma. Clin Electroencephalogr 1995;26:173-179. [ Links ] 29.[] ), occipital intermittent rhythmic delta activity (OIRDA) and temporal intermittent rhythmic delta activity (TIRDA) ( Fig 3 ).[]

  • Brain Neoplasm

  • Cerebral Neoplasm

    They include: Headache Hearing loss Impaired speech (i.e., dysphasia) Incontinence Mental and emotional changes (e.g., indifference, disinhibition) Prolonged drowsiness (somnolence[] This is a sac of cerebrospinal fluid (CSF), which has been "trapped" outside or inside the brain. It might also be called a "leptomeningeal cyst."[] ., without symptoms), but some may cause impaired speech and seizures.[]

  • Metabolic Encephalopathy

  • Limbic Encephalitis

    Symptoms and signs include eye movement abnormalities, ptosis, dysphagia, dysarthria, ataxia, facial palsy, vertigo, hearing impairment, reduced consciousness, and hypoventilation[] Cerebrospinal fluid test results were abnormal in 18 (78%) of 23 patients tested.[] Abnormalities in cerebrospinal fluid and electroencephalogram were commonly observed (92% for both). Tumors were not identified in any cases.[]

  • Mucormycosis
