The occasional slight movement of the head. What's going on?

The occasional slight shaking of the head may be caused by excessive pressure. Nowadays, many people are faced with great pressure in life and work. It is easy to cause people to suffer from long-term lack of sleep and mental tension, causing nervous tension in the brain and affecting the neck muscles. If the human body is overtired and highly excited, it will also show occasional slight shaking of the head. The occasional slight shaking of the head may also be caused by insufficient blood supply to the brain. Hypertension, hyperlipidemia, cerebrovascular disease patients due to cerebrovascular disease, or increased blood viscosity, will cause different degrees of insufficient blood supply to the brain, so stimulate the brain nerves, causing occasional slight shaking of the head symptoms. The occasional slight shaking of the head may also be considered Parkinson's syndrome, which is a common neurological disease in the elderly and should be treated as soon as possible.
