The epileptic encephalopathies comprise a group of devastating seizure syndromes which begin in infancy and early childhood and usually result in intractable epilepsy. While some syndromes are relatively easily diagnosed early in their course, others take time to evolve, hampering an early, confident diagnosis. ⋯ In these "idiopathic" cases, recurrent subtle seizures, frequent epileptiform discharge and non-convulsive status epilepticus probably all play a role in deterioration of cognitive function and evolution of behavior disorders. This paper will review the most common epileptic encephalopathy syndromes, discuss the cognitive and behavioral co-morbidities and review current therapeutic options.

Comparative Study
The reliability of ultrasound measurements of carotid stenosis compared to MRA and DSA.
Carotid ultrasound (US) is a screening test for patients with transient ischemic attacks (TIAs) or stroke who then undergo Digital Subtraction Angiogram (DSA) or Magnetic Resonance Angiography (MRA). Gold standard DSA is invasive with inherent risks and costs. MRA is an evolving technology. This study compares reliability of MRA and US modes with DSA in determining degree of internal carotid artery stenosis. ⋯ US parameters should be validated in each centre. At best, US can only approximate the accuracy of DSA, probably due to inherent limitations of this modality. Magnetic Resonance Angiography has a perfect specificity and PPV but this technique needs to be standardized. Simultaneous use of MRA and US for screening increases sensitivity to over 0.9 without compromising specificity in > 70% stenosis.

To investigate prognostic indicators in an aggressive Crooke's cell adenoma of the pituitary. ⋯ The investigation of the present case provides additional evidence that pituitary Crooke's cell adenomas may possess aggressive behavior.

Complementary and alternative medicine (CAM) is increasingly used in adults and children. Studies on CAM in neurological disorders have focused on the adult population and its use among pediatric neurology patients has not been well characterized. ⋯ The use of CAM was common among pediatric neurology patients. Over half of the families reported benefits with CAM, and side effects were perceived to be few. Physicians should initiate discussion on CAM during clinic visits so that the families and patients can make informed decisions about using CAM. Further studies should address the specific role of CAM in children with neurological disorders, and to determine the potential interactions between CAM and conventional therapies in these patients.

To survey neurosurgical practices in the treatment of chronic and subacute subdural hematoma in the Canadian adult population. ⋯ Our survey has identified variations in practice patterns among Canadian Neurosurgeons with respect to treatment of subacute or chronic subdural hematoma (SDH). Our findings support the need for further prospective studies and clinical trials to resolve areas of discrepancies in clinical management and hence, standardize treatment regimens.
