Early Onset ALS
Early Onset ALS (amyotrophic lateral sclerosis) is a rare form of the disease affecting adults younger than age 45. It is estimated to account for 10-20% of all ALS cases. The average age of onset is between 40 and 60 years. While the cause of Early Onset ALS is not known, genetic factors are thought to play a role in some cases.
Symptoms
Early Onset ALS has the same symptoms as classic ALS, but may develop more quickly. Symptoms can include muscle weakness, twitching, and difficulty with speech, swallowing, and breathing.
Diagnosis
Diagnosis of Early Onset ALS is made by a neurologist based on a combination of medical history, physical examination, and laboratory tests. MRI and PET scans may also be used to help diagnose the condition.
Treatment
Treatment of Early Onset ALS is similar to that of classic ALS, and includes medications, physical therapy, and speech therapy. In some cases, a ventilator may be necessary to help with breathing.
Prognosis
The prognosis of Early Onset ALS is similar to that of classic ALS, with most individuals surviving 2-5 years after diagnosis. However, some individuals have been known to live much longer.
