Optic ataxia in a patient with HaNDL syndrome.

We present a woman in her 40s who arrived at the emergency room with hypertension and optic ataxia. Her medical history is only relevant for obesity. Her lumbar puncture revealed high intracranial pressure and lymphocytic pleocytosis, and her neuroimaging tests, including angiography and venography, were normal. The patient improved after a cerebrospinal fluid drainage with a lumbar puncture, and her clinical manifestations resolved in parallel to the lymphocytic pleocytosis.The patient was diagnosed with a syndrome of transient headache and neurological deficits with cerebrospinal fluid lymphocytosis and fully recovered 21 days after her discharge.

Unusual complication of Herpes simplex encephalitis: complete Klüver-Bucy syndrome.

Klüver-Bucy syndrome is a rare neurobehavioral disorder caused by a bilateral temporal lobe lesion affecting the hippocampus and amygdala; clinically characterised by hyperorality, hypermetamorphosis, placidity, altered sexual behaviour, eating, disorders and visual impairment, agnosia and amnesia. However, the complete syndrome is rarely seen, and diagnosis does not require all the symptoms to be manifested simultaneously.We describe a patient who developed a complete Klüver-Bucy syndrome secondary to bilateral temporal involvement due to herpetic encephalitis.

Catatonic syndrome as the presentation of encephalitis in association with COVID-19.

COVID-19 has shown different neurological manifestations even sometimes there are the initial or the main presentation.The following case report is about a middle-aged woman who, over 3 days, developed fever, clinical neurological alterations (stupor, muteness, fixed gaze and catatonia), cerebrospinal fluid (16 lymphocytes) and an electroencephalogram (EEG) (4-6 Hz generalised activity) with characteristics of encephalitis. A serum IgG, IgM, nasopharyngeal swab PCR for SARS-CoV-2. The patient responded positively to support measures, symptomatic and corticosteroid treatment. At discharge, the patient was independent and improved considerably.We report the presence of catatonia as a possible and atypical manifestation of encephalitis in association with COVID-19.
