About This Presentation

Description : Check out this medical PowerPoint presentation titled "Amyotrophic Lateral Sclerosis (ALS)”.

This medical PowerPoint presentation is about amyotrophic lateral sclerosis (ALS), also known as Lou Gehrigs disease. Amyotrophic lateral sclerosis is a neurodegenerative disease that affects the nerve cells responsible for controlling voluntary muscle movement. It is a progressive disease, meaning it worsens over time, and it ultimately leads to muscle weakness, paralysis, and eventually respiratory failure.

The exact cause of ALS is not fully understood, but it is believed to be a combination of genetic and environmental factors. Some genetic mutations have been identified as risk factors for the disease, but most cases of ALS are not directly inherited.

The symptoms of ALS can vary from person to person, but they generally include muscle weakness, muscle cramps, twitching, and difficulty with speech, swallowing, and breathing. There is currently no cure for ALS, but there are treatments available that can help manage symptoms and improve quality of life for people with the disease.

Management of ALS often involves a team of healthcare professionals, including neurologists, respiratory therapists, speech-language pathologists, physical therapists, and occupational therapists. The goal of treatment is to maintain independence, improve function, and provide comfort and support for the person with ALS and their family.

Amyotrophic Lateral Sclerosis (ALS): Definition, Disease Progression and Prognosis Progressive fatal neurodegenerative disorder Destruction of upper and lower motor neurons in brain and spinal cord Upper motor neuron: spasticity, clonus, hyperreflexia Lower motor neurons: weakness, atrophy, fasciculation No known cure
Slide 3-

ALS: Definition, Disease Progression and Prognosis 80% limb onset; 20% bulbar onset Progressive involvement all limbs and axial muscles Progressive impairment oral, pharyngeal and respiratory muscles Loss of ability to speak, swallow and breathe Complete dependency for ADLs and near total paralysis Relative sparing of extraocular movements and bladder/bowel function Death from respiratory failure Tiryaki E, Horak H.

ALS: Definition, Disease Progression and Prognosis Median survival 3-5 years Highly variable survival times Prognosis can be modified to some degree by treatment options Approximately 10% of patients with ALS survive >10 years Predictors of poorer prognosis: Older age Bulbar onset More rapid progression in early stages of disease Chio A, Logroscino G, Hardiman O, et al.

Slide 9-

Symptom Management Sialorrhea Thickened secretions Pain Muscle Cramps Spasticity Pseudobular affect
Slide 10-

Symptom Management: Sialorrhea Excessive drooling Can be managed by: minimization of sweet and sour foods which stimulate the salivary glands use of suction devices pharmacotherapy, including tricyclic antidepressants and anticholinergic medications. Botulinum toxin and radiation therapy may provide benefit in cases of severe drooling.
Slide 11-

Symptom Management: Thickened Secretions Difficulty with expectoration and mucous plugging May be exacerbated by anticholinergic medications used to treat sialorrhea. Thickened secretions can be managed by: Increasing fluid intake Air humidification Use of mucolytics, including guaifenesin and N-Acetyl cysteine. Expectoration of secretions can also be facilitated by use of a cough assist device.
Slide 12-

Symptoms: Pain Significant impact on quality of life Musculoskeletal Immobility Atrophy Increased pressure on bones and joints Interventions Attention to positioning and repositioning Gentle stretching and range of motion activities Analgesics: acetaminophen, NSAIDS, opioids
Slide 13-

Symptoms: Muscle Cramps Occur in up to 95% Stretching, positioning, massage Limited evidence: Antiepileptics (levetiracetam, phenytoin, carbamazepine) Benzodiazepines Baclofen Quinine – no longer recommended due to risk of toxicities Mexiletine Recent phase II randomized controlled study: reduction in cramp frequency and intensity Weiss MD, Macklin EA, Simmons Z, et al.

Symptoms: Spasticity Can result in pain, contractures, falls Interfere with care Stretching, positioning, massage Muscle relaxants Baclofen, tizanidine May worsen weakness
Slide 15-

Symptoms: Pseudobulbar Affect Sudden uncontrollable outbursts of laughter or crying Degeneration of corticobulbar tracts Occurs in multiple neurologic conditions Leads to embarrassment, social isolation, associated with reduced quality of life Can be mistaken for depression

ALS and Nutrition: Dysphagia and Nutrition Management Involvement of nutritionist and speech/swallowing therapist Modification of food consistency Add thickener to liquids Puree solid foods Multiple swallows with each bite Avoid distractions while eating Chin tuck and other techniques Addition of calorie rich foods Oral supplements
Slide 22-

ALS and Nutrition: Feeding Tubes Consider with weight loss, insufficient oral intake, dehydration or choking episodes Potential benefits Stabilize weight loss Improve overall survival time Possible improvement of quality of life Access for medications Can continue to eat as tolerated for pleasure without pressure of maintaining nutrition Risks: complications from procedures, blockage, infection, does not eliminate risk of aspiration.

Slide 23-

ALS and Nutrition: Feeding Tubes Discuss early in disease course Very personal decision Consider timing of placement in context of respiratory status Should be placed before vital capacity falls below 50% of predicted Increased procedure risks with declining respiratory status Review conditions under which patient might desire feeds to be withdrawn Miller RG, Jackson CE, Kasarskis EJ et al.

Summary ALS benefits from a multidisciplinary approach to care. Goals of care should be addressed early and on an ongoing basis. Despite the lack of cure, interventions exist that may prolong survival and improve quality of life.
