Which symptom is included among the six associated symptoms of GAD?

• A. Fatigue
• B. Nausea
• C. Dizziness
• D. Hallucinations

Answer: (B)

GAD is defined not only by pervasive worry but also by a set of six associated symptoms typically listed in DSM criteria: restlessness or being “keyed up,” being easily fatigued, difficulty concentrating, irritability, muscle tension, and sleep disturbance. Fatigue fits this set because constant worry and the resulting hyperarousal drain energy, leading to persistent tiredness that often accompanies trouble sleeping and heightened muscle tension. Nausea, dizziness, and hallucinations aren’t part of these six core associated symptoms. Nausea and dizziness can occur with anxiety in some individuals, but they aren’t among the standard six, and hallucinations would point toward another issue, such as a psychotic spectrum condition. So fatigue is the symptom that belongs to the six associated symptoms.
