Collectively , the literature reveals pre clinical and clinical evidence for various phytomedicines modulating GABA-pathways , with comparative anxiolytic effect to the current array of pharmaceuticals , along with good safety and tolerability profiles
Anxiety disorders are chronic and functionally disabling conditions with high psychological stress , characterised by cognitive symptoms of excessive worry and focus difficulties and physiological symptoms such as muscle tension and insomnia .
Gamma-aminobutyric acid ( GABA ) is an inhibitory neurotransmitter within the central nervous system and is a key target of pharmacotherapies in the treatment of anxiety .
Although current pharmaceutical treatments are often efficacious , they may cause undesirable side effects including cognitive decrements and withdrawal symptoms .
Plant-based " phytomedicines " may provide novel treatment options , to act as an adjunctive or alternative to existing anxiolytic medications .
As such , we conducted a systematic review to assess the current body of literature on anxiolytic phytomedicines and /or phytoconstituents .
Influence of psychiatric comorbidity on recovery and recurrence in generalized anxiety disorder, social phobia, and panic disorder: a 12-year prospective study.
OBJECTIVE The authors sought to observe the long-term clinical course of anxiety disorders over 12 years and to examine the influence of comorbid psychiatric disorders on recovery from or recurrence of panic disorder , generalized anxiety disorder , and social phobia . METHOD Data were drawn from the Harvard/Brown Anxiety Disorders Research Program , a prospect i ve , naturalistic , longitudinal , multicenter study of adults with a current or past history of anxiety disorders . Probabilities of recovery and recurrence were calculated by using st and ard survival analysis methods . Proportional hazards regression analyses with time-varying covariates were conducted to determine risk ratios for possible comorbid psychiatric predictors of recovery and recurrence . RESULTS Survival analyses revealed an overall chronic course for the majority of the anxiety disorders . Social phobia had the smallest probability of recovery after 12 years of follow-up . Moreover , patients who had prospect ively observed recovery from their intake anxiety disorder had a high probability of recurrence over the follow-up period . The overall clinical course was worsened by several comorbid psychiatric conditions , including major depression and alcohol and other substance use disorders , and by comorbidity of generalized anxiety disorder and panic disorder with agoraphobia . CONCLUSIONS These data depict the anxiety disorders as insidious , with a chronic clinical course , low rates of recovery , and relatively high probabilities of recurrence . The presence of particular comorbid psychiatric disorders significantly lowered the likelihood of recovery from anxiety disorders and increased the likelihood of their recurrence . The findings add to the underst and ing of the nosology and treatment of these disorders
