Which criteria is included for both a DSM 5 and an ICD-10 diagnosis of panic disorder?

Choice A reason: While the DSM 5 requires at least 1 month of persistent concern or worry about additional panic attacks following at least one attack, the ICD-10 criteria traditionally focus more on the frequency of attacks over a specific period. The 1-month worry criterion is a specific diagnostic threshold emphasized more heavily in the DSM nomenclature. Choice B reason: Avoidance behaviors, specifically a significant maladaptive change in behavior related to the attacks, is a core criterion in the DSM 5. ICD-10 also recognizes the impact of panic on behavior, but the specific phrasing regarding "avoidance behaviors" to prevent attacks is a primary structural component of the DSM-5 diagnostic framework. Choice C reason: Dizziness and palpitations are individual symptoms that can occur during a panic attack. While they are common, they are part of a larger list of possible symptoms. A diagnosis is not made based on these two symptoms alone, but rather on meeting a specific numerical threshold of symptoms from a standardized list. Choice D reason: Both the DSM 5 and the ICD-10 require the presence of at least 4 out of a list of 13 recognized physical and cognitive symptoms to classify an episode as a "panic attack." This requirement ensures that the episode is distinguished from limited-symptom attacks and represents a sufficiently intense surge of fear or discomfort for a formal diagnosis.
