26 hours ago · Amyotrophic lateral sclerosis (ALS) is a rare neurodegenerative disorder affecting the upper and lower motor neuron. It leads to progressive muscle weakness with atrophy. Most patients present as limb-onset ALS (70%), and the remaining ones present as bulbar-onset ALS, which usually manifests with dysarthria and/or dysphagia. >> Go To The Portal
Do not hesitate to discuss any medical or mental concern with your ALS doctor. Living well with ALS means doing everything possible to cope with symptoms as they occur, if not before. Managing the symptoms is the mainstay treatment for ALS; multidisciplinary care may improve quality of life.
For more information abuot finding clinical trials on ALS, visit www.clinicaltrials.gov. Use the search terms “amyotrophic lateral sclerosis” or “ALS AND (your state)” to locate trials in your area.
Physicians may prescribe medications to treat these symptoms, as well as other symptoms often associated with ALS — including drooling, anxiety and depression, constipation (the result of reduced mobility and/or weakened abdominal muscles), sleep difficulties and pain associated with prolonged immobility.
ALS often starts in the hands, feet or limbs, and then spreads to other parts of your body. As the disease advances and nerve cells are destroyed, your muscles get weaker. This eventually affects chewing, swallowing, speaking and breathing.
Bulbar symptoms manifesting as dysarthria or dysphagia are the most common ALS presentation next to limb involvement, affecting 20-25% of patients. Rarely, patients with ALS may present with respiratory muscle weakness, generalized weakness, or difficulty with head control.
Early symptoms include:Muscle twitches in the arm, leg, shoulder, or tongue.Muscle cramps.Tight and stiff muscles (spasticity)Muscle weakness affecting an arm, a leg, the neck, or diaphragm.Slurred and nasal speech.Difficulty chewing or swallowing.
Blood, Urine and Other Tests Blood tests are used to look for evidence of other diseases whose symptoms are similar to early signs of ALS. These include tests for thyroid and parathyroid disease, vitamin B12 deficiency, HIV, hepatitis, auto-immune diseases, and some types of cancer.
Abnormalities in muscles seen in an EMG can help doctors diagnose or rule out ALS . An EMG can also help guide your exercise therapy. Nerve conduction study. This study measures your nerves' ability to send impulses to muscles in different areas of your body.
What Are the Main Types?Sporadic ALS is the most common form. It affects up to 95% of people with the disease. Sporadic means it happens sometimes without a clear cause.Familial ALS (FALS) runs in families. About 5% to 10% of people with ALS have this type. FALS is caused by changes to a gene.
ALS can start off with something as simple as a weak feeling in your hands or feet. It's a disease that attacks the brain cells that control a lot of your muscle movement. Eventually, ALS (amyotrophic lateral sclerosis or Lou Gehrig's disease) weakens the diaphragm, a muscle needed for your lungs to work.
Electromyography: EMG is one of the most important tests used to diagnose ALS. Small electric shocks are sent through your nerves. Your doctor measures how fast they conduct electricity and whether they're damaged. A second part of the test also checks the electrical activity of your muscles.
What are the symptoms? The onset of ALS may be so subtle that the symptoms are overlooked. The earliest symptoms may include fasciculations (muscle twitches), cramps, tight and stiff muscles (spasticity), muscle weakness affecting a hand, arm, leg, or foot, slurred and nasal speech, or difficulty chewing or swallowing.
Raised serum CK concentrations are also found in ALS patients. In the present study, 43% of ALS patients had a CK concentration above the upper limit of the normal range. This is consistent with previous studies that reported 23–70% of ALS patients could have raised CK levels (2, 3, 5–10).
ALS often starts in the hands, feet or limbs, and then spreads to other parts of your body. As the disease advances and nerve cells are destroyed, your muscles get weaker. This eventually affects chewing, swallowing, speaking and breathing.
Amyotrophic Lateral Sclerosis and the Eye. As discussed above, ALS affects not only motor neurons, the spinal cord, the cerebellum, and large areas of the brain but also the visual system, including the oculomotor and visual pathways.
When ALS begins in the bulbar motor neurons, localized in the brainstem, the muscles used for swallowing and speaking are affected first. Rarely, symptoms begin in the respiratory muscles. As ALS progresses, symptoms become more widespread, and some muscles become paralyzed while others are weakened or unaffected.
Amyotrophic lateral sclerosis (ALS) is a rare neurodegenerative disorder affecting the upper and lower motor neuron. It leads to progressive muscle weakness with atrophy. Most patients present as limb-onset ALS (70%), and the remaining ones present as bulbar-onset ALS, which usually manifests with dysarthria and/or dysphagia. Approximately, 10% of all ALS cases are familial, and the disease may be inherited in an autosomal-dominant, recessive, or X-linked way. 1 ALS is diagnosed clinically, and the diagnosis is supported with electromyography (EMG) findings. Klippel–Feil syndrome (KFS) is characterized by fusion of cervical vertebrae, short neck, and low posterior hairline. 2,3 Mutations in a transcription factor protein-coding mesenchyme homeobox 1 gene have been shown to cause an autosomal recessive subtype of KFS (KFS2, Online Mendelian Inheritance in Man ( OMIM 214300). 4,5 Recently, 2 types of autosomal-dominant KFS were linked to other mutations. KFS1 (OMIMs 118100) is caused by a mutation in the Growth Differentiating Factor-6 (GDF6) gene, whereas KFS3 (OMIM 613702) has a mutation in the GDF-3 (GDF3) gene. 6,7 Some KFS cases are caused by chromosomal rearrangement. 8–10
Approximately, 10% of all ALS cases are familial, and the disease may be inherited in an autosomal-dominant, recessive, or X-linked way. 1 ALS is diagnosed clinically, and the diagnosis is supported with electromyography (EMG) findings.
The guidelines include information about drug, nutritional, and respiratory therapies; multidisciplinary care; symptom management; and cognitive/behavioral impairment.
Medical interventions and technology have vastly improved the quality of life for people with ALS by assisting with breathing, nutrition, mobility, and communication. Proper management of symptoms and proactive use of medical interventions and equipment can make a positive difference in day-to-day living, ...
As the diaphragm and intercostal muscles weaken in ALS, the act of breathing, which is entirely automatic for most people, becomes conscious and energy-consuming. To preserve quality of life (and to prolong life itself in later stages of ALS) introducing preventive measures to maintain breathing becomes necessary.
Living well with ALS means doing everything possible to cope with symptoms as they occur, if not before. Managing the symptoms is the mainstay treatment for ALS; multidisciplinary care may improve quality of life.
In the event that a patient presents with weakness in the muscles of their mouth, another breathing test called maximal sniff nasal inspiratory force ( SNIF, also called the sniff nasal pressure), avoids the need for a mouthpiece.
Instead, the person with ALS may become unduly angry or irritable or may be less considerate of others than one might expect them to be, or may exhibit poor judgment, apathy, ritualistic habits, new dietary preferences, or other uncharacteristic behavior. ALS is related to frontotemporal dementia (FTD).
ALS is related to frontotemporal dementia (FTD). Both are progressive neurodegenerative diseases, characterized by degeneration of the frontal and temporal lobes of the brain. ALS and FTD lead to a disturbance in behavior, personality, and language.
Cognitive and behavioral changes. ALS often starts in the hands, feet or limbs, and then spreads to other parts of your body. As the disease advances and nerve cells are destroyed, your muscles get weaker.
Military service. Studies indicate that people who have served in the military are at higher risk of ALS. It's unclear what about military service might trigger the development of ALS. It might include exposure to certain metals or chemicals, traumatic injuries, viral infections, and intense exertion.
Amyotrophic lateral sclerosis (a-my-o-TROE-fik LAT-ur-ul skluh-ROE-sis), or ALS, is a progressive nervous system disease that affects nerve cells in the brain and spinal cord, causing loss of muscle control. ALS is often called Lou Gehrig's disease, after the baseball player who was diagnosed with it.
ALS causes the motor neurons to gradually deteriorate, and then die. Motor neurons extend from the brain to the spinal cord to muscles throughout the body. When motor neurons are damaged, they stop sending messages to the muscles, so the muscles can't function.
Dementia. Some people with ALS have problems with memory and decision-making, and some are eventually diagnosed with a form of dementia called frontotemporal dementia. By Mayo Clinic Staff. Amyotrophic lateral sclerosis (ALS) care at Mayo Clinic.
People with ALS can develop malnutrition and dehydration from damage to the muscles that control swallowing. They are also at higher risk of getting food, liquids or saliva into the lungs, which can cause pneumonia. A feeding tube can reduce these risks and ensure proper hydration and nutrition.
Some cases are inherited. ALS often begins with muscle twitching and weakness in a limb, or slurred speech. Eventually, ALS affects control of the muscles needed to move, speak, eat and breathe. There is no cure for this fatal disease.
The exact causes of ALS remain unknown. ALS results in the death of motor neurons in the brain and spinal cord. There is an increased risk of ALS in military veterans. Although ALS can affect anyone, it is more common in whites, males, and people over 60 years of age.
Amyotrophic Lateral Sclerosis (ALS) Amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig’s disease, is a progressive and fatal disease, attacking neurons that control voluntary movement. These neurons die over time. The result is the gradual loss of muscle movement, speech, swallowing, and eventually, breathing.
Prevention Tips. There is no definite method to prevent ALS. However, people with ALS can participate in clinical trials, the National ALS Registry, and the National ALS Biorepository. This participation may help researchers learn about potential causes and risk factors of the disease.
