Correlative factors of cognitive dysfunction in PD patients: a cross-sectional study from Southwest China.
Cognitive dysfunction is common in Parkinson's disease (PD). A comprehensive understanding of cognitive dysfunction and its correlative factors in Chinese PD patients were not available. ⋯ Age, sex, education level, bradykinesia score, and presence of urinary symptoms are correlative factors of cognitive dysfunction in Chinese PD patients.

Internal maxillary artery to intracranial artery bypass: a case series of 31 patients with chronic internal carotid/middle cerebral arterial-sclerotic steno-occlusive disease.
To evaluate the effectiveness of internal maxillary artery (IMA) - radial artery graft (RAG) - middle cerebral artery (MCA) bypass surgery for chronic arterial-sclerotic severe stenosis or occlusion of the internal carotid artery (ICA) or MCA. ⋯ By supplying an adequate flow to a larger flow territory of chronically stenotic/occlusive major cerebral arteries, IMA bypass surgery is efficient for restoring hemodynamics in selected patients and improving their neurological deficits.

Restless leg syndrome: a risk factor of higher prevalence of anxiety and depression in Parkinson's disease patients.
Many studies have assessed the relationship of depression and anxiety with Parkinson's disease (PD), as well as examining restless leg syndrome (RLS) with depression and anxiety. Nonetheless, there has not been an extensive effort to show how the prevalence of RLS affects both depression and anxiety in PD patients. The objective of this study was to examine how the prevalence of RLS in PD patients affects the prevalence and severity of depression and anxiety and how they compare with each other. This study is the first of its kind that examines the effects of the combination of the two neurological conditions with depression and anxiety as well as comparing their prevalence and severity to each other. ⋯ The presence of RLS in PD patients may increase the occurrence of both anxiety and depression, but the severity of the symptoms is not significant in the two groups of the PD patients.

Traumatic brain injury accelerates kindling epileptogenesis in rats.
Traumatic brain injury (TBI) is a well-known cause of symptomatic epilepsy. In animal models of post-traumatic epilepsy (PTE), progression of trauma to epilepsy takes several weeks to months. Although this long process is similar to clinical PTE, it is costly and laborious. We used a combination of TBI and kindling as an accelerated animal model to develop epilepsy in much shorter period compared to that occurring in PTE. ⋯ Traumatic brain injury facilitates acquisition of epilepsy in both chemical and electrical kindling models. Combination of trauma and kindling can be considered as an inexpensive and time-saving animal model in PTE studies.

Acute hypercarbia increases the lower limit of cerebral blood flow autoregulation in a porcine model.
In the present study, our objective was to determine if hypercarbia would alter cerebral blood flow (CBF) autoregulation and reduce the ability of cerebrovascular reactivity monitoring to identify the lower limit of cerebrovascular autoregulation (LLA). ⋯ Hypercarbia without acidosis increases the observed LLA independent of alterations in ICP. Elevations in CO2 can impair cerebrovascular autoregulation, but if there is a sufficient increase in blood pressure above the CO2 altered LLA, then autoregulation persists.
