ALS (Amyotrophe Lateralsklerose)

Amyotrophic lateral sclerosis (ALS) is the commonest form of motor neuron disease. The nerve cells in the brain and spinal cord that control voluntary muscles progressively die, so muscles weaken, waste and stiffen. Sensation, eyesight, hearing and bladder control are usually unaffected.

ALS is progressive and at present cannot be cured or halted. Medicines slow it modestly. What makes the greatest difference to length and quality of life is coordinated multidisciplinary care, especially support for breathing and nutrition, delivered close to home.

Symptome

• Weakness in one hand, such as trouble with buttons, keys or grip
• Foot drop, tripping or a heavy leg
• Slurred or nasal speech and difficulty swallowing (bulbar onset, in about a quarter of people)
• Muscle twitching (fasciculations) and cramps
• Visible thinning of muscles, often at the base of the thumb
• Stiffness and brisk reflexes
• Breathlessness lying flat, disturbed sleep and morning headaches as breathing muscles weaken
• Bursts of laughing or crying that do not match your mood
• Changes in behaviour, planning or language in a minority, overlapping with frontotemporal dementia

Ursachen und Risikofaktoren

Around 9 in 10 cases are sporadic, with no family history and no single known cause. About 1 in 10 are familial, most often due to variants in C9orf72, SOD1, TARDBP or FUS. Most people develop it between 55 and 75, and men slightly more often than women. Smoking is an accepted risk factor; military service, heavy physical exertion and some chemical exposures have been associated with ALS but are not proven causes. A toxic accumulation of the protein TDP-43 inside motor neurons is found in almost all cases.

Wie es diagnostiziert wird

• Neurological examination: Diagnosis rests on finding both upper and lower motor neuron signs spreading over time. No single test proves ALS.
• EMG and nerve conduction studies: Show active and chronic denervation in several body regions and exclude treatable neuropathies such as multifocal motor neuropathy.
• MRI of brain and spine: Excludes compression of the spinal cord, tumours and other mimics.
• Blood tests: Thyroid, B12, creatine kinase, immunology and infection screens to rule out look-alike conditions.
• Genetic testing: Increasingly offered to everyone, since a SOD1 variant opens access to tofersen.
• Breathing tests: Forced vital capacity, sniff pressure and overnight oximetry guide the timing of ventilation support.

Behandlungsmöglichkeiten

• Riluzole: A tablet taken twice daily that extends survival by a few months on average. Liver tests are monitored.
• Edaravone: Available in some countries; benefit was shown in a selected early-stage group and later studies have been less convincing.
• Tofersen: An antisense drug given by lumbar puncture for SOD1-ALS only.
• Non-invasive ventilation: A mask ventilator at night improves sleep, symptoms and survival. It is one of the most effective interventions available.
• Nutrition and gastrostomy: Dietitian input and a feeding tube placed before breathing capacity falls too far, to maintain weight.
• Therapy and equipment: Physiotherapy, occupational therapy, splints, wheelchairs, and voice banking with communication devices.
• Symptom control: Medicines for cramps, stiffness, saliva, emotional lability, pain and anxiety.
• Palliative and advance care planning: Introduced early, so that your wishes about ventilation and feeding are known.

Wenn es dringend ist

Seek emergency care locally for choking, a chest infection with difficulty clearing secretions, increasing breathlessness, or new confusion and drowsiness, which can indicate carbon dioxide retention. Tell emergency staff that you have ALS, since uncontrolled high-flow oxygen can be harmful.

Reisen nach Türkiye zur Behandlung

Be cautious. No clinic anywhere can reverse ALS, and stem cell treatments sold for it are experimental, unproven in controlled trials and carry real risks. A trip can reasonably provide a diagnostic second opinion, with repeat EMG, MRI and genetic testing over 2 to 4 days, which matters because a few mimics are treatable. Ongoing care has to be local, regular and responsive, and as the condition advances long flights themselves become hazardous because of reduced breathing reserve.
