asthenia/경색증

BACKGROUND Pure arm monoparesis is an uncommon presentation of stroke. Localization of the lesions is variable, including cortical, subcortical or deep brain infarcts. No particular risk factors or unifying mechanisms have been clearly identified. METHODS Seven patients (5 women, 2 men) presented

Objective: A better understanding of factors influencing breathing weakness in stroke survivors would help in planning rehabilitation therapies. The main objective of this study was to determine whether the location of cerebral infarct is

We describe isolated unilateral axial weakness in three patients eventually diagnosed with anterior cerebral artery infarction (ACAI), a new clinical observation. Files of three ACAI patients (2 females, 1 male, ages 55-80) were retrospectively reviewed. All three presented to the ED with sudden

SMALL CORTICAL STROKES CAN PRODUCE PREDOMINANT ISOLATED WEAKNESS IN A PARTICULAR GROUP OF FINGERS: radial or ulnar. The traditional views are of point-to-point representations of each finger to neurons located in the precentral gyrus of the motor cortex such that the neurons of the radial fingers

Since its discovery, our understanding of the primary motor cortex has continued to evolve. The presentations of rare, isolated, motor palsies of small muscle groups have heavily contributed to the characterization of the somatotopic representation of the human body on the cortex. We present a case

Isolated facio-lingual hypoesthesia and weakness is rare. We describe a case of isolated facio-lingual hypoesthesia and weakness after a hemorrhagic infarct localized at the contralateral operculum. A 66-year-old woman developed acute onset of facio-lingual hypoalgesia, hypoesthesia, and weakness,

We reported a hypertensive 40-year-old man who developed sudden right hemiparesis, deep sensory disturbance, left hypoglossal nerve palsy, and mild right central facial weakness. MRI of the brain showed an infarct located in the left upper medullary pyramid. Course and connection of the

We describe two patients with upper medullary infarctions showing ipsilateral facial weakness and relative sparing of the upper facial muscles. Electrophysiological follow-up using transcranial magnetic stimulation of the motor cortex in combination with stimulation of the peripheral facial nerve

The purpose of this article is to draw attention to atypical presentation of medial medullary infarction (MMI). With advanced imaging techniques, small infarctions occurring in the medulla are more easily identified. It is difficult, however, to make a clinical diagnosis of MMI if both hypoglossal

A 41-year-old male presented with acute onset weakness of the left hand. Magnetic resonance imaging (MRI) of the brain showed hyperacute infarct in the right middle cerebral artery (MCA)-posterior cerebral artery (PCA) watershed territory. Magnetic resonance angiography (MRA), Doppler

Isolated hand weakness due to stroke is infrequently observed, and often misdiagnosed as peripheral lesions. This study investigated the clinical and radiologic profiles in such patients. Five men and one woman were studied. All patients underwent cranial magnetic resonance imaging (MRI) to confirm

Small cortical infarctions can produce isolated motor paresis in the upper extremities. Several cases of isolated hand or finger paresis have been reported, but isolated shoulder weakness is extremely rare. We report here a patient who developed isolated shoulder weakness due to a small cortical

Heart failure induced by myocardial infarction (MI) causes diaphragm muscle weakness, with elevated oxidants implicated. We aimed to determine whether diaphragm muscle weakness is 1) early-onset post-MI (i.e., within the early left ventricular remodeling phase of 72 h); and 2) associated with

BACKGROUND Infarct of the anterior spinal artery is the most common subtype of spinal cord infarct, and is characterized by bilateral motor deficits with spinothalamic sensory deficits. We experienced a case with atypical anterior-spinal-artery infarct that presented with bilateral hand weakness but

Respiratory dysfunction is prevalent in critically ill patients and can lead to adverse clinical outcomes, including respiratory failure and increased mortality. Respiratory muscles, which normally sustain respiration through inspiratory muscle contractions, become weakened during critical illness,
