Research has shown that other physical and psychological problems can frequently happen in patients with PNES. These include:
· A history of one or more head injuries;
· Fibromyalgia, headaches and other pain syndromes;
· Fatigue and cognitive changes (including problems with concentration, word finding difficulties, slurred speech, forgetfulness);
· Weakness or paralysis of a limb, numbness or tingling;
· Changes in vision, hearing or speech;
· Bowel and bladder problems;
· Significant problems with anger management, impulse control and/or assertiveness;
· High anxiety (including panic and worrying) and problems with stress coping;
· Depression and difficulty with keeping emotions steady;
· A past history of traumatic experiences (such as emotional, physical and/or sexual abuse);
· Difficulties in relationships, family dysfunction;
· Alexithymia (a difficulty in recognizing and/or verbalizing emotional experiences).
Some patients have none, a few or many of these other problems.
Treatment with PNES may also help relieving some of these other symptoms or problems.
