Poor concentration is not an illness but is a symptom that may be associated with other disorders. Poor concentration can be caused by the natural aging process, poor diet, poor blood circulation, lack of sleep, low blood sugar or stress among other things.
Massage can help with poor concentration by improving blood flow to the brain and throughout the body. Massage can also help to reduce stress and improve sleep. Conditions such as Alzheimer's or traumatic brain injury should be ruled out by a physician.
