Biological causes may include obsessive compulsive disorder, Postural Orthostatic Tachycardia Syndrome, post traumatic stress disorder, hypoglycemia, hyperthyroidism, Wilson's disease, mitral valve prolapse, pheochromocytoma, and inner ear disturbances (labyrinthitis). Dysregulation of the norepinephrine system in the locus ceruleus, an area of the brain stem, has been linked to panic attacks.[13]

Post-Traumatic Stress Disorder affects people after terrifying events such as physical or sexual abuse, car accidents, war or natural disasters. Individuals with PTSD may experience depression, flashbacks, nightmares, sleep difficulties, irritability, aggression, violence, and a feeling of detachment or numbness. Symptoms can be triggered by anything that reminds the individual of their trauma.
In a decision context, unpredictability or uncertainty may trigger emotional responses in anxious individuals that systematically alter decision-making.[46] There are primarily two forms of this anxiety type. The first form refers to a choice in which there are multiple potential outcomes with known or calculable probabilities. The second form refers to the uncertainty and ambiguity related to a decision context in which there are multiple possible outcomes with unknown probabilities.[46]
It should be noted that finding the right strategy that works for you to control your anxiety is important. Maybe you feel that you do not have the time to schedule "me time" with your busy schedule or kids, and you need to find another way to reduce your anxiety. A friend or therapist could be a great resource to turn to if you believe you need help with finding the right strategies to reduce your anxiety.

Separation anxiety disorder: Separation anxiety is often thought of as something that only children deal with; however, adults can also be diagnosed with separation anxiety disorder. People who have separation anxiety disorder have fears about being parted from people to whom they are attached. They often worry that some sort of harm or something untoward will happen to their attachment figures while they are separated. This fear leads them to avoid being separated from their attachment figures and to avoid being alone. People with separation anxiety may have nightmares about being separated from attachment figures or experience physical symptoms when separation occurs or is anticipated.
