Seizures and antiepileptic drugs in patients with spontaneous intracerebral hemorrhages
AbstractPurposePatients with intracerebral hemorrhage (ICH) are often initiated on antiepileptic drugs without a clear indication. We compared the percentage of patients with spontaneous ICH who had seizures at onset or during hospitalization, and examined empiric use of antiepileptic drugs (AEDs) in these patients in 2 cohorts 10 years apart.MethodsUsing a clinical data registry at a tertiary care adult hospital, we retrospectively selected admissions for spontaneous ICH between 1/1/99–12/31/00 (Cohort A, n=30) and 1/1/09–12/31/10 (Cohort B, n=108). Clinical, neurophysiological and radiological data were collected in both cohorts.ResultsIn Cohorts A and B respectively, AEDs were started in 53.3% and 50.0%, and continued on discharge in 50.0% and 20.4% of patients; 86.6% and 59.1% of patients discharged on AEDs did not have a clinical/electrographic seizure or epileptiform EEG findings. Seizures occurred in 6.6% and 13.0% in Cohorts A and B respectively. The presence of a seizure at presentation (p=0.01) and during hospitalization (p=0.02) were predictors for continuing AED on discharge.ConclusionIn both cohorts, a significant number of patients were discharged on AEDs without a clear indication, though there is a change in practice between the two cohorts
Anomalies in the review process and interpretation of the evidence in the NICE guideline for chronic fatigue syndrome and myalgic encephalomyelitis
Chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME) is a disabling long-term condition of unknown cause. The National Institute for Health and Care Excellence (NICE) published a guideline in 2021 that highlighted the seriousness of the condition, but also recommended that graded exercise therapy (GET) should not be used and cognitive-behavioural therapy should only be used to manage symptoms and reduce distress, not to aid recovery. This U-turn in recommendations from the previous 2007 guideline is controversial.We suggest that the controversy stems from anomalies in both processing and interpretation of the evidence by the NICE committee. The committee: (1) created a new definition of CFS/ME, which 'downgraded' the certainty of trial evidence; (2) omitted data from standard trial end points used to assess efficacy; (3) discounted trial data when assessing treatment harm in favour of lower quality surveys and qualitative studies; (4) minimised the importance of fatigue as an outcome; (5) did not use accepted practices to synthesise trial evidence adequately using GRADE (Grading of Recommendations, Assessment, Development and Evaluations trial evidence); (6) interpreted GET as mandating fixed increments of change when trials defined it as collaborative, negotiated and symptom dependent; (7) deviated from NICE recommendations of rehabilitation for related conditions, such as chronic primary pain and (8) recommended an energy management approach in the absence of supportive research evidence.We conclude that the dissonance between this and the previous guideline was the result of deviating from usual scientific standards of the NICE process. The consequences of this are that patients may be denied helpful treatments and therefore risk persistent ill health and disability

The Role of the Neurologist after Diagnosis
Psychogenic nonepileptic seizures (PNES) are the most frequent type of paroxysmal events misdiagnosed as epileptic seizures. Neurologists are usually the initial contact in the care of patients with these events, as they are often able to recognize or suspect that they are not epileptic seizures and conduct a diagnostic evaluation. Unfortunately, many neurologists (and epileptologists) continue to believe that their work is finished when the diagnosis of PNES is established. In fact, the neurologists’ role only begins when the diagnosis is made. This chapter highlights the various roles that neurologists should play in the care of PNES patients during and following a diagnostic evaluation. It emphasizes the need for followup visits which ensure the patients’ understanding and acceptance of the diagnosis. The neurologist should promote continuity of care, allow for management of other functional neurological symptoms and neurological comorbidities, ensure rational pharmacological therapy with antiepileptic drugs, promote communication among healthcare providers, and avoid iatrogenic interventions

Recurrent Epileptic Auras As a Presenting Symptom of Alzheimer’s Disease
Seizures are a common co-morbidity during the course of Alzheimer’s disease (AD) and in a subset of patients may be one of the presenting symptoms. In this case series, we highlight three patients with recurrent medically refractory epileptic auras whose work up ultimately lead to the diagnosis of AD. All three patients underwent prolonged EEG, serial neuropsychological testing, FDG-PET, cerebrospinal fluid (CSF) AD biomarkers, and MRI. CSF biomarkers were particularly helpful in two cases. These cases highlight the importance of having a high index of suspicion for AD in new onset “idiopathic” epilepsy in the elderly
Functional neurological disorder: new subtypes and shared mechanisms.
Functional neurological disorder is common in neurological practice. A new approach to the positive diagnosis of this disorder focuses on recognisable patterns of genuinely experienced symptoms and signs that show variability within the same task and between different tasks over time. Psychological stressors are common risk factors for functional neurological disorder, but are often absent. Four entities-functional seizures, functional movement disorders, persistent perceptual postural dizziness, and functional cognitive disorder-show similarities in aetiology and pathophysiology and are variants of a disorder at the interface between neurology and psychiatry. All four entities have distinctive features and can be diagnosed with the support of clinical neurophysiological studies and other biomarkers. The pathophysiology of functional neurological disorder includes overactivity of the limbic system, the development of an internal symptom model as part of a predictive coding framework, and dysfunction of brain networks that gives movement the sense of voluntariness. Evidence supports tailored multidisciplinary treatment that can involve physical and psychological therapy approaches
