A major twin study found the concordance was greater for monozygotic (24 purchase isoptin 40 mg otc blood pressure after exercise. Neuroimaging: a meta-analysis of functional imaging (Etkin & Wagner 2007) in social anxiety disorder generic 40 mg isoptin amex arteria bulbi urethrae, specific phobia and PTSD found that in all three disorders, hyperactivity was identified in the amygdala and insula. A study (Liao et al, 2011) found, in social anxiety disorder, decreased grey matter volumes. However Frick et al (2013) found significantly increased thickness of the left inferior temporal cortex in social anxiety disorder relative to controls, and a negative association was found between social anxiety symptom severity and thickness of the right rostral anterior cingulate cortex. The course is chronic and unlikely to remit without treatment. Treatment with antianxiety medication and CBT which involves a component of exposure may be beneficial. Pharmacological treatment gives more rapid relief, CBT treated patients are at less risk of relapse. Demarcation between shyness and social phobia may be difficult/impossible. Non- generalized social phobia, is a term applied when symptoms are limited to specific situations such as public speaking. Interestingly, most individuals believe they are more nervous than others (Stein et al, 1994). There is a risk of medicalizing the human condition. Diagnosis should be limited to situations where individuals experience “significant distress and functional impairment”. Commonly feared objects include animals, insects, heights, injections/blood, and dental procedures, etc. Marked fear or anxiety about a specific object or situation (flying, spiders, injections) B. The phobic object or situation almost always provokes immediate fear. Phobic object avoided or endured with intense anxiety D. Many individuals with simple phobias are able to live a relatively normal life, making minor adjustments to avoid the feared object. Specific phobias tend to co-occur with other specific phobias. Most common are the situational/environmental phobias, followed by animals and injection/blood phobias. Age of onset appears to vary with the nature of the phobia. Animal phobia has the earliest age of onset +/- 7 years of age. Genetic contributions are detectable, but also vary with the nature of the phobia. Neuroimaging: Functional neuroimaging, using symptom provocation paradigms, has shown abnormal activations in brain areas involved in emotional perception and early amplification - mainly the amygdala, anterior cingulate cortex, thalamus, and insula (Del Casale et al, 2012). Different neural substrates may differentiate SPs from other anxiety disorders and separate SP subtypes from one another. Specific phobias are the most treatable of the anxiety disorders. The latter may be difficult to arrange, in which case imaginal exposure is an effective alternative. Relaxation during exposure is an important component. Benzodiazepines have been used to reduce anxiety to enable patient co-operation with exposure. BLOOD/INJECTION PHOBIA Blood/injection phobia appears to be a special case. In all other phobias, exposure is associated with increased sympathetic activity - with elevated BP and pulse. In blood/injection phobia, following brief sympathetic activity, parasympathetic activity predominates, leading to vasovagal syncope.

They are characterized by repeated hurtful actions between peers where a power imbalance exists purchase isoptin 240mg amex heart attack song, and being bullied is considered a significant stressful life experience buy 240mg isoptin otc arrhythmia junctional. Bullying appears to be common, and is reported by 13% of children and adolescents during a school year world wide (Craig et al, 2009). Direct bullying (physical acts) is more common among boys and indirect bullying (exclusion and ostracism) is more common among girls. Genetic factors Genetic factors have been identified in many childhood psychiatric disorders. Separation anxiety, which is known to be influenced by environmental factors (including paternal absence), has significantly heritable components in large twin studies (Eley et al, 2003; Cronk et al, 2004). Attention Deficit/Hyperactivity Disorder is familial and highly heritable, and the disorder is being refined to identify phenotypes for use in the search for susceptibility genes (Thapar et al, 2006). Associations have been reported with variations in genes for the dopamine receptors 4 (DRD4) and 5 (DRD5) and a dopamine transporter (DAT1) (Collier et al, 2000). The most robust of these is the association between ADHD and a repeat within the coding region of DRD4 (Faraone et al, 2001). Twin studies report MZ concordance rates of 60-90% compared with DZ concordance of 5%, giving an estimated heritability of over 90% (Rutter et al, 1999). There is some evidence for a locus on chromosome 7 and another on chromosome 2, but multiple genes of small effect is the probable mechanism (Klauck, 2006). For the latest on the genetics of autism and Tourette syndrome, see State (2010). DNA is wrapped around histone proteins to form chromatin. The state (condensation) of the histones causes the DNA to be more tightly or loosely packed – resulting in regulation of access to particular genes, thereby influencing gene expression. Histones condensation is achieved by methylation, acetylation and other chemical changes, and may remain life-long [and in some circumstances, may be inherited]. Hoffmann and Spengler (2012) summarize, “(e)arly social life experiences become embedded in the circuitry of the developing brain and are associated with lifelong consequences”. A study (Wang et al, 2012) of the first two years of life found a range of individual variation in genome-wide methylation. It is also suggested that maltreatment of children may produce epigenetic changes which result in mental health and physical disorders later in life (Yang et al, 2013). These children may have significantly different methylation marks. Separation anxiety disorder In DSM-5, Separation anxiety disorders is listed under “Anxiety Disorders”. Separation anxiety in characterized by inappropriate or excessive anxiety which occurs when the child is separated from the people or home to which he/she has developed strong emotional attachment. It may be seen when children first begin to attend school, but may occur at other stages. There may be recurring distress at the anticipation of separation, or worry about losing the subject of attachment. There may be fear about being alone, refusal to sleep separate from the attachment figure, or nightmares about separation. There may be complaints of physical symptoms when separation is imminent. Separation anxiety is often managed by advice on parenting skills. Separation anxiety is difficult to distinguish from generalized anxiety in children (some regard these as synonymous terms). In the epidemiology study of Silva and Stanton (1997) separation anxiety was reported at 3. In a recent report (Keeton et al, 2009) generalized anxiety was reported at 10%, with a mean age of onset at 8. A combination of CBT and SSRI is recommended, with the continuation of medication for 1 year following remission of symptoms.

Some hyperactive-impulsive or inattentive symptoms that caused impairment were present before age 7 years.

In summary cheap isoptin 240mg with mastercard blood pressure medication with the least side effects, patients and professional participants are concerned about the impact of the social environment and circumstances of patients generic 120mg isoptin otc blood pressure apple watch, and see it as important. There is no clear agreement on the acceptability of discussions about the social environment and finances in patient and nurse consultations. Although there is general recognition of the impact of the social environment for the practice population, the perceived availability of resources (or lack of resources) that professionals can connect patients to is likely to be a driver in whether or not and how these issues are discussed and addressed. Patient views on the Patient Centred Assessment Method implementation in long-term condition annual reviews Patient and professional participants were asked to describe the ways in which conversations about their broader biopsychosocial experience would fit into the current relationship between nurse and patient, and into the current delivery of care for patients living with LTCs, particularly in relation to annual reviews. For patients, contact with primary care was described as usually being in the form of doctor visits, nurse visits or condition-specific nurse-led clinics. Patients also described having their annual review, in which there were checks of their health, including a check of their feet and eyes for those with DM. There was a mix of views on whether or not the care being provided was sufficient. Some participants, particularly those who had been fairly recently diagnosed with their condition, felt that there should be more careful monitoring of how they were managing their health. Others appeared very satisfied with the amount of care they received, and described having useful referrals put in place for things like exercise. Some participants seemed to be much more proactive than others at connecting to their GP surgery and asking for the help they needed, whereas others were hoping that there would be more outreach to them as a patient, to check on how they were managing their condition. Participants were asked to describe their experience of engaging with primary care in relation to managing their LTC. In general, participants spoke about valuing their doctors and felt pleased with the care they provided overall. It was particularly valued when it was possible to have continuity in care, and when patients felt that they had enough time to talk about their health concerns with the doctor and that they were treated as an individual and with compassion.

Patient 19 Some described feeling that the doctor was the authority figure in the clinic, the one that makes key decisions about medication and care, or who might express concerns about how the patient is managing their condition. Those participants who had talked about rejecting their diagnosis also described avoiding the doctor to avoid such interactions, even if they knew it might have negative consequences. Nurses were described as having more personal relationships with patients, with more time to spend with them during regular reviews and check-ups. The relationship was described as one in which there was more accessibility, time and generally more supportive care. Nurses were also described as suggesting activities such as exercise or weight loss, rather than being medication focused. Patient 34 In addition to the areas of discussion that might be presented by the PCAM tool, the participants reflected on how, in their view, asking such questions related to how they see the role of the nurse. Some participants felt that nurses might not have the skills and training required to ask such questions of their patients and, in that sense, it was asking nurses to go beyond their current role. However, participants were more concerned with protecting nurses from being overcommitted by being asked to do another task on top of an already significant range of responsibilities. There were concerns that nurses needed to have their time somewhat protected, and the boundaries of their role more clearly defined. There was also discussion in the focus groups about the role of nurses and what they would do with information gathered with a tool such as the PCAM. There was a sense, for some participants, that nurses should be distinguished from social workers, and not ask questions that would be more typically asked by a social worker, who was seen as more likely to act on any concerns identified by these questions. For these participants, there were concerns about nurses asking about things they might not be able to provide assistance with. Patient 34 In summary, when patient participants felt that it was appropriate to be asked the PCAM-related questions, they felt that the nurse was an appropriate role for leading that conversation. It was felt that nurses could connect patients to resources as needed, and that the supportive relationship with the nurse was conducive to talking about these topics. For those who did not feel that it was acceptable to be asked the PCAM 26 NIHR Journals Library www.
