Three years follow-up of panic disorder patients: a naturalistic study

Predictors of persistence of anxiety disorders across the lifespan: a systematic review

Despite the substantial disease burden of anxiety disorders, physicians have a poor understanding of factors that predict their typical persistent course. This systematic review of predictors of persistent anxiety disorders covered 48 studies with 29 690 patients diagnosed with an anxiety disorder that were published in PubMed, PsycINFO, and Web of Science between Jan 1, 1980 (introduction of DSM-III), and Dec 1, 2019. We also compared predictors between children, adolescents, adults, and older adults (ie, ≥55 years). A persistent course was primarily predicted by clinical and psychological characteristics, including having panic attacks, co-occurring personality disorders, treatment seeking, poor clinical status after treatment, higher severity and longer duration of avoidance behaviour, low extraversion, higher anxiety sensitivity, and higher behavioural inhibition. Unlike disorder onset, sociodemographic characteristics did not predict persistence. Our results outline a profile of patients with specific clinical and psychological characteristics who are particularly vulnerable to anxiety disorder persistence. Clinically, these patients probably deserve additional or more intensive treatment to prevent development of chronicity.

Predictors of 1-year outcome for patients with panic disorder

The course of panic disorder (PD) is often prolonged, but factors that affect the social outcome have not yet been made clear. The aim of this study was to find predictors of outcome for patients with PD. The subjects were 65 outpatients (28 men and 37 women) with PD (DSM-III-R) who were treated at our hospital for more than 1 year. The factors affecting 1-year outcome were evaluated by multiple regression analysis. We found that the following were predictors of poor social outcome in PD: (1) severe agoraphobia at the first psychiatric examination and (2) long duration of illness before the first psychiatric consultation. Furthermore, the complication of hypochondriacal symptoms predicted a poor outcome for PD. Early attention to agoraphobia and hypochondriasis is essential for the treatment of PD, and early introduction to psychiatric treatment is recommended.

Panic disorder: the ultimate anxiety

Panic disorder, an intense exacerbation of anxiety accompanied by a variety of physical symptoms, is twice as common among women as among men. Onset is bimodal (teens/20 s and mid-30 s/40 s), 50% of cases are accompanied by agoraphobia, and the etiology is probably multifactorial. Treatment in the primary care setting includes pharmacologic (selective serotonin reuptake inhibitors) and cognitive-behavioral intervention. Medication is initiated at low doses, and the drug-evaluation trial is of 6 weeks duration. Psychiatric referral is helpful in nonresponders and in those with comorbid psychiatric conditions. Outcome varies, with most patients experiencing relief with treatment. For some people, however, the disorder is chronic, with ongoing exacerbations and remissions.
