Diagnosis and management of motor neurone disease

23 Sep 2016Paid-up subscribers

Motor neurone disease is a rapidly progressive and fatal neurodegenerative condition which causes progressive weakness, with normal sensation. Key clinical presentations include bulbar (slurred or difficult speech, problems swallowing, tongue fasciculation), limb (typically in one limb with weakness and muscle wasting), respiratory (breathlessness, chest muscle fasciculation) and cognitive features (behavioural change, emotional lability, features of frontotemporal dementia).

Tailor treatment to the patient with neuropathic pain

23 Sep 2016

Neuropathic pain is defined as pain that is caused by a lesion or disease of the somatosensory nervous system and is estimated to affect 6-8% of the general population. A low threshold of suspicion in conditions associated with neuropathic pain can aid diagnosis. Typical neuropathic descriptors include burning, shooting, electric shock pain with numbness, pins and needles or itching.

Early accurate diagnosis crucial in multiple sclerosis

24 Sep 2015Registered users

In around 85% of cases, multiple sclerosis (MS) starts with an acute neurological episode, a clinically isolated syndrome, which is considered to be the first clinical episode of relapsing-remitting MS. It is characterised by the presence of acute relapses, after which there is normally good functional recovery. Investigations need to rule out conditions that can mimic an inflammatory-demyelinating disease of the CNS and determine the presence of dissemination in space and dissemination in time of the inflammatory-demyelinating disease. There is no confirmatory test for MS and it remains essentially a clinical diagnosis.

Seizure classification key to epilepsy management

24 Sep 2015Registered users

The diagnosis of epilepsy is often incorrect, potentially in up to 20% of cases, so should be revisited if seizures are not responding to treatment. SIGN recommends that the diagnosis of epilepsy should be made by an epilepsy specialist, ideally in the setting of a dedicated first seizure or epilepsy clinic. Diagnosis relies primarily on the history. Distinguishing between a genetic generalised epilepsy and a focal epilepsy is vital as this influences investigation, treatment and prognosis.

Improving outcomes for chronic pain in primary care

23 Sep 2014Registered users

Although the patient’s goal is often complete pain relief, this is rarely a realistic outcome, so the role of the physician in managing chronic pain involves optimising pain relief as far as possible. A thorough biopsychosocial assessment is essential so that an individualised multidisciplinary approach to management can be developed. The aims of assessment of chronic pain are to rule out any underlying serious pathology, identify the pain mechanism and identify and evaluate risk factors that contribute to chronicity.

Migraine is underdiagnosed and undertreated

23 Sep 2014Paid-up subscribers

Migraine is a common neurovascular disorder characterised by attacks of head pain that are typically unilateral and often described as severe and throbbing in association with nausea and sensitivity to sensory input, i.e. light, sound and head movement. NICE guidelines recommend adopting the stepped-down approach to management. They suggest a combination of a triptan, NSAID or paracetamol, and an anti-emetic taken as early as possible during the headache. [With external links to the evidence base]

Community stroke rehabilitation helps patients return to work

23 Sep 2013Paid-up subscribers

A quarter of stroke survivors are under the age of 65 meaning that many are in work and/or have responsibility for caring for children or elderly parents. With a comprehensive rehabilitation team, patients with more complex or severe disability can be rehabilitated in the community providing that the home environment can be suitably adapted. The core components of a community-based programme can be broadly defined as improving emotional wellbeing, communication, cognitive function and physical independence and supporting return to work.

Managing patients with cluster headache in primary care

23 Sep 2013Paid-up subscribers

Cluster headache is a strictly unilateral headache that occurs in association with cranial autonomic features. The diagnosis is purely clinical and it is therefore crucial to take a good history looking for its distinctive features. Specialist advice should be sought at first presentation for confirmation of diagnosis, development of a plan for managing current and future cluster bouts and where first-line treatments fail.

Diagnosing and managing muscular dystrophy

20 Sep 2012Paid-up subscribers

Muscular dystrophy refers to a range of muscle diseases caused by defects in muscle proteins, leading to death of the muscle cells, with loss of muscle tissue, and weakness. Muscular dystrophy may present at any age from perinatal to old age. The muscular dystrophies all have a genetic basis, although not all causes have been identified. Patients may present in primary care undiagnosed, or with a diagnosis and established disability when transferring practice. The development of clinical symptoms is usually gradual, and the earliest features may be difficult to identify and determine. With established disease the presence of muscle weakness and wasting is clear. In children, the presentation may be delayed walking or poor performance in sporting activity. In children and adults presenting symptoms may include: difficulty raising from a squat;difficulty raising from a chair; difficulty lifting arms above the head; poor balance; drooping eyelids; joint contractures.

Rapid diagnosis of TIA reduces risk of subsequent stroke

19 Sep 2012Paid-up subscribers

A transient ischaemic attack (TIA) is defined as a stroke that recovers completely within 24 hours of onset. TIA and stroke are the same disease and both need to be treated with equal urgency. Patients with ongoing symptoms and signs at the time of assessment, however early after onset and even if improving, need to be treated as stroke with rapid transfer to an inpatient stroke service.

GPs have key role in managing motor neurone disease

21 Sep 2011Paid-up subscribers

Motor neurone disease (MND) is a rapidly progressive neurodegenerative condition. It affects people of all ages, but is more common with increasing age (especially over 50 years) and men are affected twice as often as women. The prevalence is relatively low, as individuals usually live for only a few years with MND. There are around 1,200 new diagnoses a year, and 4,000 people affected at any one time in the UK. It will probably become more frequent with an ageing population, and the prevention of death from vascular and other causes. The Motor Neurone Disease Association has a network of regional care advisers, and visitors, and can provide support and information for the GP. MND is a devastating physical condition, and can have equally devastating effects on emotions, also affecting family, friends, and members of the multidisciplinary team. Some patients experience difficulties accessing resources, which the GP may help in mobilising. There may also be problems in understanding and communication, where the GP may play a key role.

Evaluating first seizures in adults in primary care

20 Sep 2011Paid-up subscribers

Many patients experiencing a first seizure will present to their GP. A seizure is defined as the clinical manifestation resulting from an excessive and abnormal discharge of a population of neurones. The individual lifetime risk of developing a non-febrile seizure is around 5% and approximately a third of patients will go on to experience further seizures and hence be diagnosed as having epilepsy. When evaluating a patient with a first seizure an accurate history is key and other potentially life-threatening diagnoses, especially cardiac disease, must be ruled out. Patients who have fully recovered should be directly referred to a first seizure clinic, where further tests and AEDs may be considered. Doctors should provide support and advice to the first seizure patient and be aware of the medical and social consequences of a diagnosis of seizures or epilepsy. Patients who have not recovered from their seizure, have an abnormal examination, or about whom there is diagnostic doubt, should be referred to the emergency department or specialist services for further investigations including brain imaging and lumbar puncture.

History central to diagnosing myasthenia gravis

21 Sep 2010Paid-up subscribers

MG has a prevalence of around 20 per 100,000, so an average UK practice may expect to have only one patient. The condition is treatable. The incidence is bimodal with a 2:1 female to male ratio in the younger population and a reversed sex ratio over the age of 60. The reported incidence has been increasing since the mid-1980s, mainly because of increased recognition of late-onset disease. However, the condition is probably still underrecognised in the very elderly and may be mistaken for other disorders such as stroke, motor neurone disease or Parkinson's disease.

Systematic approach needed to establish cause of vertigo

20 Sep 2010Paid-up subscribers

Vertigo is a common but complex challenge. In one postal survey of  patients from general practice, 7% reported at least one episode of vertigo in the past year. A full-time GP may expect to encounter 10-20 cases of vertigo each year and it is often seen as a potentially difficult symptom to diagnose and manage. The first problem is that the terms vertigo, dizziness, giddiness and imbalance are used in different ways by different clinicians. Dizziness and vertigo are often used interchangeably by both patients and clinicians (including the authors). The second problem is that the control of balance is complicated and diagnosing the cause of a balance disorder can take time which is usually at a premium in most clinics. Third, vertigo can be caused by many different pathologies, some of which are potentially life threatening, and it is managed by several specialties. However, much of this can be overcome by using a logical, systematic approach to the diagnosis and subsequent referral or management of the patient.

Tailor treatment to the patient with migraine

Migraine is a common, disabling primary headache disorder. it affects 15% of the UK population (7.6% of men and 19.1% of women) and is especially prevalent in patients 1 Migraine is a chronic disease with episodic manifestations. The natural history tends to follow a waxing and waning course, with patients experiencing phases of infrequent attacks and/or chronic headaches interspersed with attack-free remissions.2 Migraine can be classified into two major subtypes, with and without aura, occurring in 20-30% and 70-80% of cases, respectively.Other clinically important variants include chronic migraine, basilar and hemiplegic migraine, migraine in pregnancy and menstrual migraine.

Exercise beneficial for restless legs syndrome

21 May 2008Paid-up subscribers

Restless legs syndrome has an estimated prevalence of 10-15% in the general population;2 this equates to around nine million affected adults in the UK. It is equally common in men and women,3 although it is associated with pregnancy, which increases lifetime prevalence in women. There is an age-related increase in prevalence, so it is more often seen in middle-aged and elderly patients.1 It may affect children and adolescents,4 although formal recognition may take years as in many patients the symptoms are mild and vague. Patients with early-onset restless legs syndrome often have a family history of the condition.5 There is no known anatomical pathology associated with restless legs syndrome.
