Entire Body System

  • Pain

    If pain develops as the disease progresses (for example, if pain occurs when a person has to sit in one position too long), benzodiazepines, which are mild sedatives, may be used. [msdmanuals.com]

    Pain may result from muscle contractures and secondary effects on joints. Muscle cramps occur in almost all patients and may cause severe pain and sleep disturbance. Physical therapy can ameliorate many of the painful symptoms of ALS. [aafp.org]

    We ask about general symptoms (anxious mood, depressed mood, fatigue, pain, and stress) regardless of condition. Last updated: May 13, 2019 [patientslikeme.com]

    Pain often goes under-recognised and undertreated. It is thought to be due to spasticity but other mechanisms may be operant. [patient.info]

Musculoskeletal

  • Muscle Twitch

    Muscles twitch (called fasciculations). Muscle tone typically increases, and muscles tend to become stiff and tight, leading to muscle spasms (called spasticity). Movements are stiff and clumsy. [msdmanuals.com]

    ALS may start with intermittent muscle twitching, weakness and in some cases slurred speech. [physio-pedia.com]

    The earliest symptoms include muscle twitching, cramping, stiffness, or weakness. Affected individuals may develop slurred speech (dysarthria) and, later, difficulty chewing or swallowing (dysphagia). [ghr.nlm.nih.gov]

    Some of the early symptoms include: fasciculations (muscle twitches) in the arm, leg, shoulder, or tongue muscle cramps tight and stiff muscles (spasticity) muscle weakness affecting an arm, a leg, neck or diaphragm. slurred and nasal speech difficulty [ninds.nih.gov]

  • Muscle Spasm

    Muscles twitch (called fasciculations). Muscle tone typically increases, and muscles tend to become stiff and tight, leading to muscle spasms (called spasticity). Movements are stiff and clumsy. [msdmanuals.com]

    Baclofen may reduce muscle spasms in some patients. Patients troubled by leg cramps may benefit from quinine compounds. [rarediseases.org]

  • Hyperreflexia

    On physical exam, signs of hyperreflexia, spasticity, fasciculations, and muscle atrophy are present in an asymmetric fashion. Tongue fasciculations are also present. No sensory loss is noted. [medbullets.com]

    The diagnostic process consists of a history and physical examination, repeated at regular intervals, to document progressive hyperreflexia, fasciculations, and upper and lower motor neuron involvement. [aafp.org]

    Clinical manifestations include progressive weakness, atrophy, fasciculation, hyperreflexia, dysarthria, dysphagia, and eventual paralysis of respiratory function. [icd10data.com]

    Clinical Loss of fine motor skills, triad of atrophic weakness of hands and forearms; leg spasticity; generalised hyperreflexia. Management Possibly riluzole. [medical-dictionary.thefreedictionary.com]

[…] and support There is no cure for motor neurone disease, but treatment can help reduce the impact the symptoms have on your life. [nhs.uk]

It is not in any way intended to be used as a substitute for professional medical advice, diagnosis, treatment or care. Our staff consists of biologists and biochemists that are not trained to give medical advice . [uniprot.org]

Treatment There is no cure for ALS, and no treatment that can significantly alter its course. [medical-dictionary.thefreedictionary.com]

At the visit, write down the name of a new diagnosis, and any new medicines, treatments, or tests. Also write down any new instructions your provider gives you. Know why a new medicine or treatment is prescribed, and how it will help you. [cedars-sinai.edu]

Prognosis

This cautious approach is understandable, given the prognosis of the illness and the devastation that being given the diagnosis may cause to a person's life. [patient.info]

[…] hyperintensity in the corticospinal tracts (specificity 6 GRE/SWI: hypointensity in the precentral gyrus bilaterally, known as the " motor band sign " 8,9 MR spectroscopy 2 decreased NAA decreased glutamate increased choline increased myo-inositol Treatment and prognosis [radiopaedia.org]

Multidisciplinary clinics 17 and noninvasive ventilation for those with respiratory failure ameliorate the prognosis slightly. [touchneurology.com]

Age at diagnosis continues to be the strongest predictor of prognosis; recall case reporting bias may play a role in estimates of survival time. [raredr.com]

Alternative treatment Given the grave prognosis and absence of traditional medical treatments, it is not surprising that a large number of alternative treatments have been tried for ALS. [medical-dictionary.thefreedictionary.com]

Etiology

The etiology of amyotrophic lateral sclerosis is likely to be multifactorial, involving both genetic and environmental factors. The disease is inherited in 5-10% of the cases. [uniprot.org]

[…] ncomms/2015/150610/ncomms8319/full/ncomms8319.html About the CRCHUM The Université de Montréal Hospital Research Centre (CRCHUM) improves the health of adults through a high-quality academic research continuum which, by improving our understanding of etiological [nouvelles.umontreal.ca]

ALS is extremely rare, and the diagnostic odyssey can be rather arduous because other masquerading conditions or explanations often must be ruled out before ALS is formally diagnosed. 1, 2 The etiology or cause of nerve cell destruction in ALS remains [mybiosource.com]

Etiology ALS may have a multifactorial etiology or may result from a number of different neuronal insults. The major lines of investigation include genetic, viral, autoimmune 11 and neurotoxic hypotheses. [aafp.org]

Prognosis is poor; previous estimates of median survival from disease onset to death range from 20 to 48 months.[ 1 – 3 ] In most cases etiology is unknown, although a small proportion of cases appear to be of genetic origin.[ 4 ] A recent estimate of [raredr.com]

Epidemiological predictions show that the incidence of ALS is going to increase in the next ten years, and this increase is going to stem from disease-specific findings rather than economic conditions or health care services [ 4, 10 ]. [hsj.gr]

Pathophysiology

Progress has been made in understanding the genetic defects and the pathophysiology of this crippling motor neuron disease (commonly called Lou Gehrig’s disease). [nejm.org]

Numerous trials have targeted pathophysiological processes, but there have been no recent successes. [touchneurology.com]

Shrinkage and discolouration of the anterior nerve roots in the spinal cord occurs because of axonal degeneration of the neurones and the accompanying demyelination. [8] The pathophysiology behind the disease appears to be multi-factorial with complex [physio-pedia.com]

Pathophysiology This is a degenerative condition that affects motor neurons, namely the anterior horn cells of the spinal cord and the motor cranial nuclei. [patient.info]

Immediate and additional causes of death were categorized using an author-developed algorithm based on pathophysiology and potential relevance to patients with advanced ALS ( Table 1 ). Table 1. [raredr.com]

Treatment and prevention There is no cure for ALS, so treatment aims to alleviate symptoms, prevent unnecessary complications, and slow the rate of disease progression. [medicalnewstoday.com]
