A drug typically used to treat enlarged prostates and high blood pressure has shown promise as a potential new therapy for motor neuron disease (MND)—also known as amyotrophic lateral sclerosis (ALS)—according to a new study. MND is a group of rare diseases that destroy nerve cells known as motor neurons, causing patients to slowly lose function of their muscles. In studies using zebrafish, mice and stem cell models, experts have demonstrated that the drug terazosin protects against the death of motor neurons by increasing their energy production. Researchers say the drug could help to slow the progression of a disease...
