Brain injuries may cause a general progressive weakness in our overall physical states. People may notice that they don’t feel as strong as before and they’re suffering muscular dystrophy. This means that their muscles are shrinking and seemingly wasting away. It isn’t very comforting to experience so that’s why it’s important to find out the cause.
Neurological problems including brain cancer can trigger this progressive weakness. It also makes muscles more susceptible to damage so that’s essential for gymgoers to know. Ideally, patients will seek treatment before they experience this long-term symptom. However, that’s not always possible and chemotherapy may also trigger it (via Oxford Academic).
