PRIMARY OBJECTIVES To examine the scope of paediatric traumatic brain injury (TBI) as a health concern and to identify prognostic factors for TBI-related sequelae. METHODS AND PROCEDURES The study was prospective and nationwide. A questionnaire was sent to a study group (SG) of all 0-19 years old in Iceland, diagnosed ∼16 years earlier with TBI during a(More)
A patient with Alzheimer's disease, who is still alive, was investigated using a battery of tests, including design-copying and identification, the Gottschaldt hidden figures, a reading test, picture identification, and identification of tachistoscopically presented figures. The main observations were (i) an inability to handle more than one "element" of(More)
AIMS To estimate differences in the incidence of recorded traumatic head injuries by gender, age, severity, and geographical area. METHODS The study was prospective and nationwide. Data were collected from all hospitals, emergency units and healthcare centers in Iceland regarding all Icelandic children and adolescents 0-19 years old consecutively(More)
PRIMARY OBJECTIVES To assess long-term effects of early traumatic brain injury (TBI) on mental health, cognition, behaviour and adjustment and to identify prognostic factors. METHODS AND PROCEDURES A 1-year nationwide cohort of all 0-19 year old Icelandic children and adolescents diagnosed with TBI in 1992-1993 (n = 550) received a questionnaire with(More)
BACKGROUND To correlate measures of insight for own psychopathology to structural and functional brain imaging findings in 21 patients with DSM-IV bipolar I disorder. METHODS Insight was assessed using the Scale to Assess Unawareness of Mental Disorder (SUMD). Resting single photon emission computed tomography (SPECT) and computed tomography (CT) was(More)
AIMS To estimate the prognostic value of injury severity, location of event, and demographic parameters, for symptoms of pediatric traumatic head injury (THI) 4 years later. METHODS Data were collected prospectively from Reykjavik City Hospital on all patients age 0-19 years, diagnosed with THI (n = 408) during one year. Information was collected on(More)
148 chronic schizophrenics admitted between 1938 and 1961 had previously been followed up. In 1972, they were re-examined, on the average 10 years after the first follow-up. 44 belonged to a series of patients studied between 1955 and 1957 with a battery of conditional reflex tests. The patients belonging to the experimental series were retested with word(More)
In the Berlevag project attemps have been made at using psycho-physiological and cognitive measures as indexes of psychiatric morbidity.--With skin conductance response, psychotics and neurotics showed signs of autonomic inhibition compared with conduct disorders and normal controls. All groups except psychotics showed cognitive effects in conditioning. No(More)
After a mean test-retest period of 16 years a sample of 39 initially chronic as well as acute/subacute schizophrenic patients showed a statistically significant normalization of associative performance. This finding was corroborated by a cross-sectional comparison between the same 39 patients and a sample of chronic schizophrenics (n = 26)) tested 16 years(More)
