For Rohan Saraogi (name changed), a creative copywriter at one of the leading advertising agencies in the country, it grew stressful; to constantly be on-the-go, and come up with new, creative campaigns for more than his fair share of client briefs. Over time, the stress of his creative job got the better of him, and Saraogi found himself thinking well within that box. This constant worry meant he was always on edge, became distant and shut out friends, family, and even co-workers.While Saraogis condition may seem like the result of a stressful job alone, if left unchecked, it can lead to serious mental health issues. And for Saraogi, his condition was later diagnosed as Generalised Anxiety Disorder (GAD).What is it?GAD is anxiety and stress caused over a long duration of time, owing to the things happening around you, no matter how big or small. According to Dr Mehezabin Dordi, clinical psychologist, rehabilitation and sports medicine department, Sir HN Reliance Foundation Hospital, GAD is a form of severe, ongoing anxiety that causes intense distress, discomfort, and interferes with daily activities (social, occupational, or other important aspects of functioning). It is also known as Chronic Anxiety Neurosis.Difference between GAD and anxietyBefore diagnosing someone, its important to understand the difference between GAD and anxiety. Dr Seema Hingorrany, a Mumbai-based clinical psychologist and trauma specialist, points out, While anxiety comes and goes, the feelings of anxiety in GAD persist over a long period of time; typically a diagnosis is made if the symptoms have been present for six months or more.Signs and symptomsThe common signs and symptoms include restlessness, listlessness, and being in a constant state of worry. Dr Shambhavi Jaiman, consultant psychiatrist at Sukoon Health, Gurgaon, elaborates, A person with GAD may experience continuous feelings of nervousness, trembling, muscular tension, sweating, lightheadedness, palpitations, dizziness, and gastric discomfort. They may also experience apprehension about going about their day, and some might constantly feel on the edge.Additionally, Dr Hingorrany states that a change in appetite and lack of concentration are two telling signs of GAD. (Lets look at this example: If a patient worries about what they should eat, something as simple as this can have an adverse effect on them, and this lack of focus can render them unproductive). GAD can interfere with a patients daily life and cripples their thought process.GAD and other mental illnessesOne may notice that some symptoms of GAD tend to overlap with other mental illnesses, like depression. These include sleep issues (insomnia or constantly sleeping), irritability, restlessness, and lack of concentration. However, a background check is important to understand the root cause.
