BACKGROUND Hemimedullary syndrome is very rare and combines the clinical features of lateral and medial medullary infarctions. In patients with hemimedullary syndrome, the presence of ipsilateral, rather than contralateral hemiplegia, is rare. OBJECTIVE To describe a patient with an infarction in the right hemimedulla with an ipsilateral motor deficit due(More)
Numerous studies using a variety of imaging techniques have reported age-related differences in neural activity while subjects carry out cognitive tasks. Surprisingly little attention has been paid to the potential impact of age-associated changes in sensory acuity on these findings. Studies in the visual modality frequently report that their subjects had(More)
The spectrum of paraneoplastic neurologic syndromes has increased with the description of encephalitis associated with antibodies against cell surface and synaptic proteins. Subacute cognitive impairment, movement disorders, late onset epilepsy and neuropsychiatric syndromes were recently linked to paraneoplastic encephalitis. Despite that, probably some(More)
In this article, we report the case history of a 44-year-old female patient with bipolar disorder who developed the so-called Syndrome of Irreversible Lithium-Effectuated Neurotoxicity (SILENT). A detailed description of our patient's neurologic status is provided at baseline (i.e. during lithium intoxication) and after one year of follow-up, confirming the(More)
Deep brain stimulation (DBS) has been widely used to control motor symptoms and improve quality of life in patients with Parkinsons disease (PD). Recently, DBS in the subthalamic nucleus (STN) has become the preferred target for patients with mixed motor symptoms. Despite resultant motor and quality of life improvements, the procedure has been associated(More)
Alexia with agraphia is defined as an acquired impairment affecting reading and writing ability. It can be associated with aphasia, but can also occur as an isolated entity. This impairment has classically been associated with a left angular gyrus lesion In the present study, we describe a case involving a patient who developed alexia with agraphia and(More)
Although not evident clinically, lesions to the prefrontal cortex cause great social and functional impairment to patients. The anterior cingulate cortex is intimately involved with motivational behavior and after injury to this area the onset of an apathetic state can be observed. This paper describes the case of a patient with traumatic brain injury to(More)
Neuroplasticity can be conceptualized as an intrinsic property of the brain that enables modification of function and structure in response to environmental demands. Neuroplastic strengthening of synapses is believed to serve as a critical mechanism underlying learning, memory, and other cognitive functions. Ex vivo work investigating neuroplasticity has(More)
AIM Acquired hepatocerebral degeneration (AHD) is an exceptional type of hepatic encephalopathies (HE). It is characterized by neuropsychiatric and extrapyramidal symptomatology similar to that seen in hepatolenticular degeneration (Wilson's disease). In this paper, we report a case of AHD with unusual presenting features. METHODS A 28-year-old man with(More)
BACKGROUND Aerobic training (AT) is a promising intervention for mild cognitive impairment (MCI). OBJECTIVE To evaluate the effects of AT on cognition and regional brain glucose metabolism (rBGM) in MCI patients. METHODS Subjects performed a twice-a-week, moderate intensity, AT program for 24 weeks. Assessment with ADAS-cog, a comprehensive(More)
