Manifestaciones de conducta disruptiva y conportamientos perturbador en población normal de 4 a 17 años de edad / Manifestations of disruptive behavior and perturbation behavior in normal populations of 4 and 17 years of age

El presente articulo presenta resultados de investigación la cual tenía como objetivo identificar casos con alta probabilidad de manifestar conductas externalizantes en la población normal, para ello se realizó una investigación de corte transversal con una muestra de 444 participantes a los cuales se aplicó el instrumento SNAP-IV (Swanson, Nolan & Pelham,1983). Los resultados sugieren: diferencias en la información suministrada por cada una de las fuentes (padres y maestros) y la presencia de conductas con alta probabilidad de riesgo que pueden ser intervenidas en el medio escolar y familiar…

Hallucinations and sleep disturbances in Parkinson's disease.

Visual hallucinations (VHs) occur frequently in Parkinson's disease (PD). VHs occur more frequently in elderly patients with longer duration of illness, cognitive impairment, and sleep disturbances. The relationship between the use of antiparkinsonian drugs and VHs is complicated, but most drugs used to treat parkinsonian motor symptoms induce VHs and psychosis in some PD patients. The "continuum hypothesis" proposing that medication-induced psychiatric symptoms in PD begin with drug-induced sleep disturbances, followed by vivid dreams, with progression to hallucinatory and delusional experiences has been challenged. In some patients, VHs may represent intrusion of REM sleep-related imagery into wakefulness. Improving REM sleep abnormalities in PD (e.g., stimulants, anticholinesterase inhibitors) is one strategy now being tested to improve VHs in PD.
