manipulation, usually administered in the course of chiropractic treatment, can cause stroke, 10 and abducens paresis may develop if there is brainstem infarction or neck vessel dissection. Since our patient had no signs of brainstem infarction and her neck vessels appeared pristine on MRI, her abducens paresis undoubtedly resulted from the intracranial hypotension per se. Ophthalmologists eval...

The pathophysiology of postictal paresis and other symptoms of Todd's phenomenon are not fully understood. Various hypotheses about its mechanism include exhaustive neuronal firing, desensitization, and active suppression. This case series demonstrates CT perfusion findings of two patients with postictal paresis that show hyperperfusion, increased cerebral blood flow, increased cerebral blood v...

1. Disorders of the iris sphincter that may require pharmacologic testing — cholinergic super-sensitivity vs. under-sensitivity: When evaluating an anisocoria that increases in bright light and decreases in dim light, attention usually shifts toward the pupil that is larger in bright light to determine if a paresis of the iris sphincter paresis is present. The causes are either from denervation...

We report a patient with general paresis, whose magnetic resonance image (MRI) showed a T2 high-intensity lesion in bilateral mesial temporal regions. Serum rapid plasma reagin test showed reactive at 64 dilutions and serum Treponema pallidum haemagglutination test was 1:20480. Cerebrospinal fluid analysis showed: RBC 111/mm3, WBC 8/mm3, Venereal Disease Research Laboratory reactive at 1 diluti...

PURPOSE To look for changes in the motor cortex in patients with brain tumors. METHODS Both cerebral hemispheres in seven patients with brain tumors were examined with functional MR imaging during a motor task performed by the hand opposite the site of tumor. The ratio of the activated area in the motor cortex ipsilateral/contralateral to the tested hand was calculated for each subject. Twent...

This individual prospective cohort study aims to report and analyze the symptoms preceding and accompanying the facial paresis in Bell's palsy (BP). Two hundred sixty-nine patients affected by BP with a maximum delay of 48 hours from the onset were enrolled in the study. The evolution of the facial paresis expressed as House-Brackmann grade in the first 10 days and its correlation with symptoms...

Diagnosis and treatment of the immobile or hypomobile vocal fold are challenging for the otolaryngologist. True paralysis and paresis result from vocal fold denervation secondary to injury to the laryngeal or vagus nerve. Vocal fold paresis or paralysis may be unilateral or bilateral, central or peripheral, and it may involve the recurrent laryngeal nerve, superior laryngeal nerve, or both. The...

We report an 84-year-old female who showed a rare manifestation of epilepsy, ictal paresis, a type of simple partial seizure presenting with focal motor dysfunction. While the patient exhibited severe left hemiplegia which lasted for a week, cranial diffusion-weighted MRI demonstrated slightly high intensity in the right posterior quadrant, and electroencephalography (EEG) showed continuous epi...

Isolated hand paresis is a rare presentation of stroke, which mostly results from a lesion in the cortical hand motor area, a knob-like area within the precentral gyrus. I report the case of a patient who experienced recurrent ischemic stroke alternately involving bilateral hand knob areas, causing isolated hand paresis. There was no abnormal finding on brain and neck magnetic resonance angiogr...

Purpose: The purpose of the study was to evaluate the efficacy of botulinum toxin type A (BTX-A) injection in patients with acquired VI nerve palsy. Methods: Twenty-eight patients (16 F and 12 M), mean age 36.4 +/− 17.8 DS; range 10 69 years with acquired VI nerve palsy, have been treated with BTX-A injection into the ipsilateral medial rectus, at least 6 months after onset. At 6 months follow ...
