Diagnosis of Amyotrophic Lateral Sclerosis (ALS) typically occurs between the ages of 40 and 70, with most cases diagnosed in individuals around 55. Symptoms often begin subtly, such as muscle weakness or twitching, leading to a gradual progression that can be mistaken for other conditions. Due to the complexity of the disease and overlap with other neurological disorders, diagnosis may take several months to years, often requiring a combination of clinical evaluation and diagnostic tests. Early recognition is crucial for management and support options.
Tremors can occur in various neurological conditions, including amyotrophic lateral sclerosis (ALS), but they are not a characteristic symptom of ALS itself. ALS primarily causes muscle weakness, muscle wasting, and stiffness due to the degeneration of motor neurons. While some individuals with ALS may experience shaking or twitching, these symptoms are not typical tremors. If tremors are present, it’s important to consult a healthcare professional for a proper diagnosis.
Some of the symptoms of ALS include twitching, muscle weakness in the hands, arms, and legs may occur also. Ones speech can be affected and alter slightly at the onset of ALS.
Lou Gehrig's diagnosis was confirmed on June 19, 1939. It was on his 36th birthday.
ALS usually progresses rapidly, and leads to death from respiratory infection within three to five years in most cases.
Stephen Hawking was diagnosed with ALS when he was 21, which was in about 1963. It is now 2012, and he is now 70. That makes him a 49 year survivor. A link can be found below for more information.
The earliest sign of ALS is most often weakness in the arms or legs, usually more pronounced on one side than the other at first.

It's highly unlikely. Lou Gehrig's diagnosis was confirmed on June 19, 1939 and it has not been disputed ever since.
Around 5,000-6,000 people die from ALS each year in the United States. It is a progressive neurodegenerative disease with no cure that primarily affects the nerve cells responsible for controlling voluntary muscles. Early diagnosis and multidisciplinary care are important in managing symptoms and improving quality of life for those affected by ALS.

Amyotrophic lateral sclerosis (ALS) can be hereditary in some cases, known as familial ALS, which accounts for about 5-10% of all cases. The majority of ALS cases are sporadic, meaning they occur without a clear genetic link. Certain genetic mutations, such as those in the C9orf72, SOD1, and TARDBP genes, have been associated with familial ALS. However, even in sporadic cases, genetic factors may still play a role alongside environmental influences.
Common symptoms of ALS include weakening of the muscles, twitching and cramping in the muscles, impairment of the use of the arms and legs, difficulty in projecting the voice and shortness of breath and difficulty breathing and swallowing. ALS is often treated through a series of medications, but none are proven to slow the progression of the disease.
