Post concussion syndrome ebb and flow: Longitudinal effects and management

This research identified persistent post concussion symptoms (PCS) in a group of 20 adult subjects. PCS generally lasted for two years with a mean of 3.35 years. Typical symptoms included physical and cognitive fatigue, depressive behaviors, sensitivity to noise, social withdrawal, irritability, concentration and problem solving difficulties, loss of libido and much difficulty making decisions at even the simplest strategic level. They represented a hard core group for whom the original symptoms persisted well beyond the 6~month period. Participants identified their PCS according to sensory, somatic affective and cognitive items immediately following their trauma (01) and two years later (02). Counseling and psychotherapy intervention took place between 01 and 02. Items on the PCS schedules and the Beck Depression Inventory (II) demonstrated significant decline in the presence of overall symptoms most noticeably in reduction of agitation, irritability and suicidal wishes. However, subjects throughout generally experienced the feeling that they were being punished which equated with behaviors comparable with learned helplessness. The PCS group considered themselves to be different people after trauma. They had different goals, changing lifestyle, relationships and employment and were more often in a dependent state. Comparability with other conditions such as PTSD and chronic fatigue syndrome (CFS) was demonstrated by individuals who experienced persistent and invasive post concussion symptoms.

Concussion incidences and severity in secondary school varsity football players.

The head coaches and players of 103 secondary school football teams in Minnesota were asked to respond to mail questionnaires. Information about injury incidence and concomitant health care provision was elicited. Responses from 3,063 players (81 per cent) yielded a total injury rate of 78 injuries/100 players; 19/100 players reported a concussion experience characterized by loss of consciousness and/or loss of awareness. Of the players who experienced a loss of consciousness, 69 per cent were returned to play the same day. Persistent concussion symptoms were reported as long as six to nine months following the end of the season; six cases involved permanent disabilities. Continued use of illegal techniques of butt-blocking and face-tackling by as many as 40 per cent of the players was associated with apparent increased risks of concussions and concussion symptoms. Players with a prior history of loss of consciousness had a risk of loss of consciousness four times that of the player without a prior history.
