ALS symptoms

Each type of motor neurone disease affects different parts of the body, particularly during the early stages of the condition. ALS, which is the most common type, initially causes muscle weakness in the arms and legs, which can cause you to trip and drop things.

ALS, which is difficult to diagnose, may then cause issues with speech and swallowing. Abnormal fatigue of the arms and/or legs, muscle cramps and twitches and uncontrollable periods of laughing or crying are common signs of ALS, especially early on.

Later, the condition may impact the breathing muscles. Permanent ventilatory support to assist with breathing may be needed in severe cases.

Wider MND symptoms

Some MND symptoms are the same, regardless of the type of the condition. The says early signs include stiff or weak hands, weak legs and feet (climbing stairs may be difficult) and muscle spasms.

While symptoms affect everyone differently, the later symptoms could include changes in your mood and personality and problems with speech. Note each symptom, despite its frequency and severity, to your GP when sharing concerns about your health.

Diagnosing all types of MND become easier as symptoms get worse. This can be challenging for doctors because a later diagnosis often means a loss of time to manage the condition, which can be crippling.

Medicines help ease symptoms, such as muscle stiffness or cramps, drooling and breathlessness. Physiotherapy and exercises help with muscle weakness and stiffness, and changes to the diet can help maintaining weight. There is no cure for MND.

But, despite his challenges, defiant actor Eric said this week: "I am grateful to have my loving family by my side as we navigate this next chapter."
