It can elicit a neuro-hormonal response understood as Flight or Fright reaction kicking in physiological cascade of symptoms ranging from palpitations, tachycardia, breathlessness, increased bowel movement, increase frequency of urination, dizziness, muscle tension or pain, trembling, dizziness, blurring of vision to restlessness, confusion and fainting spells. Chronic stress causes prolonged anxiety response with the consequences of slowed me ration, lack of concentration, headaches, fluctuations in blood pressure and increased wear and tear of body tissues. Identifying your stressors, learning to deal with them, de stressing regularly by doing something that makes one feel good, yoga and meditation are some non pharmacological strategies to deal with it. Siezures are due to electrophysiological disturbance in brain and anti convulsants are the treatment of choice. If the condition is persisting for a long time, it's better to see a psychiatrist.
