What results in either too much or little movement as exemplified by disease and disease?

Too much movement

* Hyperthyroidism: A condition in which the thyroid gland produces too much thyroid hormone. This can lead to increased heart rate, weight loss, nervousness, and anxiety.

* Parkinson's disease: A neurodegenerative disorder that affects the part of the brain that controls movement. This can lead to tremors, rigidity, and difficulty with balance and coordination.

* Huntington's disease: A neurodegenerative disorder that affects the part of the brain that controls movement and cognition. This can lead to chorea (involuntary movements), dementia, and psychiatric problems.

Too little movement

* Hypothyroidism: A condition in which the thyroid gland does not produce enough thyroid hormone. This can lead to fatigue, weight gain, constipation, and depression.

* Myasthenia gravis: A neuromuscular disorder that affects the communication between nerves and muscles. This can lead to muscle weakness and fatigue.

* Multiple sclerosis: A neurodegenerative disorder that affects the central nervous system. This can lead to muscle weakness, fatigue, and difficulty with balance and coordination.
