The American Academy of Pediatrics strongly encourages the disclosure of HIV status to school-age children and further recommends that adolescents know their HIV status. Limited information exists on the impact of disclosure. We designed and implemented a disclosure model hypothesized to be associated with healthy psychological adjustment and improved medication adherence. We report the model's design and implementation and results of a quasi-experimental study of the disclosure's effects on health care professionals (n = 16), caregivers (n = 39), and HIV-infected youth (n = 40) in Puerto Rico. Information was collected from youth, caregivers, and professionals by semistructured interviews and questionnaires. Most youth (70%) had feelings of normalcy 6 months post-disclosure, and most also improved their adherence to therapy after disclosure as reported by both patients (58%) and caregivers (59%). Eighty-five percent of youth and 97% of caregivers considered disclosure a positive event for themselves and their families. Fewer health care professionals reported feelings of fear, discomfort, and insecurity after protocol participation.
Psychogenic non-epileptic seizures (PNES) – time-limited disturbances of consciousness and motor-sensory control, not accompanied by ictal activity on electroencephalogram (EEG) – are best conceptualized as atypical neurophysiological responses to emotional distress, physiological stressors and danger. Patients and families find the diagnosis of PNES difficult to understand; the transition from neurology (where the diagnosis is made) to mental health services (to which patients are referred for treatment) can be a bumpy one. This study reports how diagnostic formulations constructed for 60 consecutive children and adolescents with PNES were used to inform both the explanations about PNES that were given to them and their families and the clinical interventions that were used to help patients gain control over PNES. Families were able to accept the diagnosis of PNES and engage in treatment when it was explained how emotional distress, illness and states of high arousal could activate atypical defence responses in the body and brain – with PNES being an unwanted by-product of this process. Patients and their families made good use of therapeutic interventions. A total of 75% of children/adolescents (45/60) regained normal function and attained full-time return to school. Global Assessment of Functioning scores increased from 41 to 67 (t(54) = 10.09; p < .001). Outcomes were less favourable in children/adolescents who presented with chronic PNES and in those with a chronic, comorbid mental health disorder that failed to resolve with treatment. The study highlights that prompt diagnosis, followed by prompt multidisciplinary assessment, engagement, and treatment, achieves improved outcomes in children/adolescents with PNES.
Psychogenic non-epileptic seizures (PNES) are a common problem in paediatric neurology and psychiatry that can best be understood as atypical responses to threat. Threats activate the body for action by mediating increases in arousal, respiration, and motor readiness. In previous studies, a range of cardiac, endocrine, brain-based, attention-bias, and behavioral measures have been used to demonstrate increases in arousal, vigilance, and motor readiness in patients with PNES. The current study uses respiratory measures to assess both the motor readiness of the respiratory system and the respiratory regulation of CO2. Baseline respiratory rates during clinical assessment and arterial CO2 levels during the hyperventilation component of routine video electroencephalogram were documented in 60 children and adolescents referred for treatment of PNES and in 50 controls. Patients showed elevated baseline respiratory rates [t(78) = 3.34, p = .001], with 36/52 (69%) of patients [vs. 11/28 (39%) controls] falling above the 75th percentile (χ 2 = 6.7343; df = 1; p = .009). Twenty-eight (47%) of patients [vs. 4/50 (8%) controls] showed a skewed hyperventilation-challenge profile—baseline PCO2 <36 mmHg, a trough PCO2 ≤ 20 mmHg, or a final PCO2 <36 mmHg after 15 min of recovery—signaling difficulties with CO2 regulation (χ 2 = 19.77; df = 1; p < .001). Children and adolescents with PNES present in a state of readiness-for-action characterized by high arousal coupled with activation of the respiratory motor system, increases in ventilation, and a hyperventilation-challenge profile shifted downward from homeostatic range. Breathing interventions that target arousal, decrease respiratory rate, and normalize ventilation and arterial CO2 may help patients shift brain–body state and avert PNES episodes.Electronic supplementary materialThe online version of this article (doi:10.1007/s00787-017-0976-0) contains supplementary material, which is available to authorized users.
Psychogenic non-epileptic seizures (PNES) are a nonspecific, umbrella category that is used to collect together a range of atypical neurophysiological responses to emotional distress, physiological stressors and danger. Because PNES mimic epileptic seizures, children and adolescents with PNES usually present to neurologists or to epilepsy monitoring units. After a comprehensive neurological evaluation and a diagnosis of PNES, the patient is referred to mental health services for treatment. This study documents the diagnostic formulations – the clinical formulations about the probable neurophysiological mechanisms – that were constructed for 60 consecutive children and adolescents with PNES who were referred to our Mind-Body Rehabilitation Programme for treatment. As a heuristic framework, we used a contemporary reworking of Janet’s dissociation model: PNES occur in the context of a destabilized neural system and reflect a release of prewired motor programmes following a functional failure in cognitive-emotional executive control circuitry. Using this framework, we clustered the 60 patients into six different subgroups: (1) dissociative PNES (23/60; 38%), (2) dissociative PNES triggered by hyperventilation (32/60; 53%), (3) innate defence responses presenting as PNES (6/60; 10%), (4) PNES triggered by vocal cord adduction (1/60; 2%), (5) PNES triggered by activation of the valsalva manoeuvre (1/60; 1.5%) and (6) PNES triggered by reflex activation of the vagus (2/60; 3%). As described in the companion article, these diagnostic formulations were used, in turn, both to inform the explanations of PNES that we gave to families and to design clinical interventions for helping the children and adolescents gain control of their PNES.
Children and adolescents with conversion disorders and their families are challenging to understand and challenging to treat. This study examined whether self‐report instruments are a useful adjunct to family and individual assessment. A total of 57 children and adolescents diagnosed with conversion disorders and 57 sex‐ aged‐matched controls, along with their parents, completed the Strength and Difficulties Questionnaire, Child Behaviour Checklist, Depression Anxiety and Stress Scales, Somatic and Psychological Health Report (SPHERE), Brief Risk‐Resilience Index for Screening, and the NEO–Five‐Factor Inventory. The conversion disorder and control groups were compared on each questionnaire, and classified participants as ‘cases’ or not according to established clinical thresholds for each questionnaire. A discriminant analysis was used to examine which components of the SDQ, CBCL, DASS, SPHERE, BRISC, and NEO‐FFI emerged as most useful in identifying the clinical characteristics of children with conversion disorders. The role of attachment strategy with regards to the utility of self‐report measures was also examined. The SPHERE was the only self‐report that our patient cohort were able to utilise to communicate their somatic and emotional discomfort and distress. Our results suggest that children and adolescents presenting with functional somatic symptoms represent a distinctive clinical population for which the ‘psychological’ focus of most currently available questionnaires is not useful for identifying the presence of somatic illness or of comorbid anxiety and depression, and that these measures – with the exception of the SPHERE – are not a useful adjunct to a family‐based assessment. Therapeutic conversations that utilise language that asks about the state of the body – the body's response to stress, illness, pain, and injury – facilitate engagement and serve as the cornerstone of treatment.
