Nervousness
The cause of nervousness may be either psychological or physical. Psychological causes include emotional conflicts, lack of a goal in life, lack of a sense of belonging, an awareness of thwarted ambition, or mental, depression.
Nervousness is often associated with fatigue. Nervousness often occurs in connection with an overactive thyroid. It may accompany chronic systemic diseases such as tuberculosis. It commonly occurs in dietary insufficiencies and accompanies diseases or injuries to the brain such as encephalitis, brain tumor, or head injury.
