Cardiac arrest is a leading cause of death that affects more than a million individuals worldwide every year. Despite the recent advancement in the field of cardiac arrest and resuscitation, the management and prognosis of post-cardiac arrest brain injury remain suboptimal. ⋯ Considering that a potentially broad therapeutic window for neuroprotective drug therapy is offered in most successfully resuscitated patient after cardiac arrest, the need for further research is imperative. The aim of this article is to present the major pathophysiological disturbances leading to post-cardiac arrest brain injury, as well as to review the available pharmacological therapies.

Comparative Study
Dementia is associated with insulin resistance in patients with Parkinson's disease.
Parkinson's disease is a neurodegenerative disorder involving the basal ganglia. Type-2 Diabetes Mellitus is an important risk factor for Alzheimer disease and vascular dementia. However, the association between Parkinson's disease and Diabetes Mellitus is controversial. ⋯ Our study suggests that PD patients with dementia are two times more likely to have insulin resistance than patients with PD.

The most common neurological injuries associated with roller coaster rides are subdural hematoma and cervical artery dissection. We report two cases of roller-coaster associated subarachnoid hemorrhage (SAH). A 40-year-old healthy man developed a strong, holocephalic headache during a roller coaster ride. ⋯ In conclusion, SAH is a rare but relevant differential diagnosis in cases of acute headache during roller coaster rides. Both aneurysmal and non-aneurysmal perimesencephalic SAH can occur. A combination of mechanical factors and excessive blood pressure rises in vulnerable persons is discussed.

A 55-year-old woman complained of right scapular pain, like burning, radiating down his right arm and numbness in the first three fingers of the hand. Neurologic examination showed a slight deficit of the right brachial triceps muscle. Neurophysiological assessment showed a mild involvement of the seventh right spinal root (C7). ⋯ High resolution MR neurography with multiplanar reconstruction along the course of the right brachial plexus showed a mild increase in signal intensity and thickening of the C7 root, middle trunk and posterior cord, consistent with Parsonage-Turner Syndrome. STIR images showed increased signal intensity in the right infraspinatus muscle innervated by the suprascapular nerve. In our case, sensitivity and specificity of the new MR sequences are higher than the clinical and neurophysiological evaluations.

Meta Analysis
Thrombolysis rate and impact of a stroke code: a French hospital experience and a systematic review.
Intravenous rt-PA is effective in hyperacute ischemic stroke (HAIS) but is administered only in few patients. ⋯ Thrombolysis rate of HAIS is improved by a SC, especially when a prenotification system of thrombolysis candidates by Emergency Medical Services to the stroke unit is used.
