Epigenetics Epigenetics is of great interest throughout psychiatry – a process by which gene expression can be altered without alteration of the DNA sequence accupril 10mg. All anxiety disorders may be influenced by experience generic 10mg accupril mastercard, and evidence suggest that some anxiety disorders may be underpinned by epigenetic marks/mechanisms (McGhee and Bell cheap 10 mg accupril with mastercard, 2014; Hommers et al, 2015). Amygdala structures: 1) BLA (Basolateral Amygdala complex), and CeA (Central Amygdala). The neurobiology of anxiety and anxiety disorders is yet to be fully explained. The amygdala, in the median temporal lobe, is activated by threatening stimuli. Patients with anxiety disorders activate the amygdala in response to given stimuli more than non-anxious controls. It is composed of a number of nuclei, including the basolateral amygdala complex (BAL) and the central nucleus of the amygdala (CeA). The BAL receives negative emotional signals from the thalamus, and the sensory association cortex. It (BAL) activates the CeA, which in turn activates the bed nucleus of the stria terminalis (BNST). Neurons from both the CeA and the BNST project to the brainstem, hypothalamus and basal forebrain. Activation of the brainstem and hypothalamus structures produces the somatic manifestations of anxiety (tachycardia etc). Activation of basal forebrain nuclei (ventral tegmental area and locus ceruleus) may produce the dysphoria of anxiety. Further, the medial prefrontal cortex (mPFC) and anterior cingulate cortex (ACC) both send input to and receive input from the BAL. The mPFC can modulate the activity of the BLA (and the anxious experience). The mPFC may enable conscious and unconscious control of anxiety. Pregnenolone, which is secreted by the adrenals is an example; others are believed to be produced by nervous system cells. The above illustration is provided for any trainee psychiatrist who may be slumming. The subgenual cortex refers to the cortex inferior to the anterior bend (L. Palomero- Gallagher et al (2015), using cytoarchitectural methods have identified region s32 as being associated with fear processing (and s24 as being associated with sadness). Neuroimaging In GAD, amygdala connection variations have been observed, including increased connectivity to the parietal lobe, and decreased connection with the insula and cingulate. Further, the CeA may have increased volume (Etkin et al, 2009). A recent DTI study (Trop do, et al, 2012) found bilateral decreased functional connectivity between the anterior cingulate cortex and the amygdala – specifically, in GAD; the integrity of the uncinate fasciculus was reduced. Alemany et al (2013) report volume reductions observed in the bilateral fusiform gyrus and the amygdala in mz twins concordant for anxiety. Psychosocial mechanisms Stressful life events may trigger GAD. The greater the number of negative life events experienced, the greater the likelihood of GAD (Blazer et al, 1987). A healthy parent-child relationship leads to the child developing a sense of control over the environment and a repertoire of adaptive responses. In the absence of such a relationship and development, the child may be vulnerable to anxiety (Chorpita & Barlow, 1998). In a large study (Yonkers et al, 1996), the mean age of onset was 21 years and the average duration was 20 years. Although 80% received treatment, only 15% remitted after one year, and 27% had remitted after 3 years. Remission rates are even lower in the presence of comorbid psychiatric disorders. Treatment Self-help books and activities may have a place (Hirai & Clum, 2006). Psychological treatments take many forms, from a behavioural approach at one end of the spectrum, to psychodynamic psychotherapy at the other. Most therapists would claim to use some form of cognitive behaviour therapy (CBT). The original feature of cognitive therapy was the challenging of illogical and self-defeating thinking. However, the term CBT has absorbed a number of earlier stand alone treatments such as relaxation therapy, hypnosis, patient education, and even systematic desensitization (once the cornerstone of behaviour therapy), and it has emerged into an eclectic, and effective, active treatment. Acceptance and Commitment Therapy (ACT) is an emerging form of talking therapy (based unsurprisingly on acceptance and commitment, and employing mindfulness and behaviour change) which is proving effective (A-Tjak et al, 2015). Pharmacological treatments are helpful in the majority of cases. Alcohol is the most widely used substance in the management of anxiety - however, long-term use worsens anxiety and precipitates depression, in addition to serious physical consequences, and is discouraged. Antianxiety drugs are described in a separate chapter. Until recent years the term antianxiety drugs was synonymous with benzodiazepines. However, for various reasons (some substantiated and others not) various antidepressants (escitalopram, fluoxetine, paroxetine, sertraline and venlafaxine) are now regarded to be the first line pharmacological agents (Canadian et al, 2006). PANIC DISORDER The term panic comes from the Greek god, Pan. He was also the god of nightmares, and took pleasure in frightening (panicking) people in the woods. Panic symptoms were first described by Hippocrates circa 400 BC, and panic is known in all cultures. Pan, a Greek god who enjoyed frightening (panicking) people and animals. He was (perhaps is) part man and part goat (ears, legs and horns).
