Neurostimulation for Refractory Cervicogenic Headache: A Three-Year Retrospective Study.

Background: Occipital nerve stimulation (ONS) has been used for the treatment of neuropathic pain conditions and could be a therapeutic approach for refractory cervicogenic headache (CeH).

Aim: The aim of this study is to assess the efficacy and safety of unilateral ONS in patients suffering from refractory CeH.

Methods: We conducted a retrospective chart review on patients implanted from 2011 to 2013 at CHUM.

A Nursing Intervention Increases Quality of Life and Self-Efficacy in Migraine: A 1-Year Prospective Controlled Trial.

Objectives: To compare the impact of a combined nursing and medical approach to a medical follow-up only on headache outcomes, quality of life, and self-efficacy in a cohort of migraineurs.

Background: Interdisciplinary approaches have been proposed for migraine management. A nursing intervention could improve patient outcomes.

Canadian Headache Society systematic review and recommendations on the treatment of migraine pain in emergency settings.

Background: There is a considerable amount of practice variation in managing migraines in emergency settings, and evidence-based therapies are often not used first line.

Methods: A peer-reviewed search of databases (MEDLINE, Embase, CENTRAL) was carried out to identify randomized and quasi-randomized controlled trials of interventions for acute pain relief in adults presenting with migraine to emergency settings. Where possible, data were pooled into meta-analyses.

Diurnal cycle of salivary cortisol in older adult men and women with subjective complaints of memory deficits and/or depressive symptoms: relation to cognitive functioning.

In populations of young and older adults, it has been shown that individuals may be categorized into one of three diurnal subgroups when salivary cortisol levels are assessed over a 2-day period and compared for their consistency across days: a typical subgroup, a flat subgroup, and an inconsistent subgroup. Interestingly, recent studies have reported that the typical subgroup represents the majority of the young and older adult population, a finding that is difficult to reconcile with previous studies showing increased cortisol levels in older adults with depression or cognitive impairments. In order to assess whether a typical diurnal cortisol profile is representative across different subgroups of older adults, we assessed diurnal cortisol cycle representation in a sample of older adults with subjective complaints of depression and/or memory problems.

Functional and anatomical memory indices in patients with or at risk for Alzheimer's disease.

We investigated the sensitivity of the P300 event-related brain potential (ERP) recorded during a memory-demanding task to memory function in subjects with dementia of the Alzheimer's type (DAT), those with mild cognitive impairment (MCI), and normal elderly controls. We also explored the ability of neuropsychological (delayed verbal memory), neuroanatomical (MRI-based hippocampal volume), and electrophysiological (memory search P300 amplitude) memory measures to distinguish between the three subject groups using discriminant function analyses. Fourteen patients with DAT, 16 with MCI, and 15 age- and education-matched controls were tested.
