Anxiety

Everything Shrinkopedia knows about anxiety, in one place.

Reviewed by Shariq Refai, MD, MBA

Anxiety is the most common category in mental health and one of the most heterogeneous. This hub exists to give the category a single clinical landing page, so the work of figuring out which anxiety condition fits, what the symptoms are, and which treatments have evidence doesn't require digging through dozens of fragmented entries.

Anxiety isn't one thing. It's a category that holds at least eight distinct conditions, dozens of symptoms, several evidence-based treatments, and a vocabulary that's specific enough that getting the words right is part of the work.

Most people who land on a page about anxiety arrived there from a single experience, a panic attack, a worry that wouldn't stop, a social situation that left them shaking. The page they need first depends on where they started. This hub is the map: it points you to the condition entries, the symptom explanations, the treatments with evidence, and the glossary terms that connect them.

Read whatever's most relevant first. If you're not sure where to start, the conditions section below is usually the right place.

Treatment Overview

Anxiety has some of the most studied treatment evidence in mental health. For most anxiety disorders, the first line approach is cognitive behavioral therapy plus or minus an SSRI or SNRI. CBT, when it includes the exposure based components matched to the specific disorder (interoceptive exposure for panic, social exposures for social anxiety, situational exposure for specific phobias), produces durable remission for the majority of patients who complete a full course. SSRIs and SNRIs work for the majority of patients within 6 to 12 weeks. Benzodiazepines have a limited role for short term use during crises or as a bridge while an SSRI is reaching effect; long term use is generally avoided because of tolerance and dependence risks. Buspirone is an option for generalized anxiety specifically. Beta blockers can help with performance anxiety. Hydroxyzine is a non addictive option for as needed anxiety relief. Lifestyle factors (sleep, exercise, alcohol use, caffeine intake) substantially affect anxiety and are part of the treatment plan.
