Soldiers who developed “shell shock” during the world wars were in fact experiencing PTSD. Other causative triggers include violent personal assaults (mental or physical), natural disasters, accidents and other horrific events.
Generalized anxiety disorder
Characterized by chronic anxiety, exaggerated worry and tension even when there is little to provoke it this often presents with symptoms which include recurring headaches, irritability, sweating, twitching and several others. Some symptoms are very vague, and patients can at times present to the GP, physician or surgeon with symptoms which resemble organic disease.
Obsessive compulsive disorder (OCD)
Often characterized by recurrent unwanted thoughts and images (obsessions) and / or repetitive behaviours (compulsions), this can become a very distressing condition both for the sufferer as well as the people living and working with them.
People experiencing OCD are often observed following particular rituals such as repetitive washing of hands, counting objects, tidying things up and aligning articles in an orderly fashion. These rituals typically provide immediate and temporary relief.
Patients typically experience unexpected and repeated episodes of intense fear accompanied by physical symptoms such as chest pains, shortness of breath, heart palpitations and other symptoms that seem to simulate a heart attack.
