Which of the following is true regarding panic disorder in children?
AlladinOne [14]

Answer:

A. Children report more cognitive symptoms than adults, is true regarding panic disorders in children.

Explanation:

A. Children report more cognitive symptoms than adults.  

Children with panic disorder are more anxious as compared to adults even when they are not having panic attacks. They report severe cognitive symptoms such as fear of an attack, reluctance to perform well in school, avoiding certain places due to fear of attack called agoraphobia, depression, substance abuse and suicidal behaviors. Hence, children may also need psychotherapy along with panic disorder medications so that they could control their anxiety. Early treatment of panic disorder with cognitive behavioral therapies may prevent complications such as agarophobia, and depression in children.  

B. Children experience only cued panic attacks.  

Both children and adolescents have unexpected panic attacks which might be triggered by anything which causes anxiety in them. They should have varying periods of fear and discomfort which might last minutes to hours.  

C. Children may report a general fear of becoming sick rather than specific physical symptom

A child suffering from panic attacks may have heart-attack like symptoms with a racing heart, fear of death and losing control, obsessive-compulsive symptoms, and physical symptoms including nausea, vomiting, dizziness, shortness of breath etc. Moreover, children are also left with an intense fear of another panic attack which might trigger these symptoms. Thus, they become less functional and has a fear of changing places, habits as anything might trigger their symptoms. So, children are more anxious about the physical symptoms ensuing the panic attack and tries their best to avoid it.
