Attentional and neuromotor deficits in ADHD.

In order to classify attention-deficit-hyperactivity disorder (ADHD) in 11-year-old children, the role of specific attentional and motor deficits was examined. Participants comprised 22 children with ADHD (19 male, 3 female; median age 11 years, range 8.8 to 13.5 years) and 20 control children (17 male, 3 female; median age 10.6 years, range 8.2 to 12.6 years). Neuromotor assessment indicated that while both groups needed more time to complete finger compared to hand movements, this increase was more pronounced in children with ADHD. Reaction-time testing with continuous-force recording identified both motor and attentional deficits in children with ADHD. Longer intervals between force onset and force peak, and higher rate of responses with multiple force peaks (particularly in the bilateral condition) revealed specific deficits in the speed and quality of their motor output. Increase in errors and variability of force onsets indicated attentional deficits. Prediction analysis indicated that force-onset variability contributed significantly to group classification which was 85.7% correct. Neither neuromotor assessment nor specific motor deficits contributed significantly to classification, indicating that pure motor-speed measures play a minor role in characterizing ADHD in this age range.

A 5-year-old girl with interstitial deletion of 3p14: clinical, psychologic, cytogenetic, and molecular studies.

An interstitial deletion of segment 3p14 (breakpoints 3p21.1 and 3p13) was found in a 5-year-old short, microcephalic, and mentally retarded girl with a pattern of anomalies comprising a wide forehead, short up-slanting palpebral fissures, small nose and ears, hypoplasia of larynx, trachea, and bronchi, clino- and camptodactyly of little fingers, and sacral vertebral fusion. Determination of microsatellites mapping to the deleted segment demonstrated that the deletion had occurred in the paternal germ line. This is the seventh patient with a deletion of 3p14, and comparison with the six previously reported cases does not yet allow definition of a specific pattern of minor and major anomalies.

Acrodermatitis chronica atrophicans.

Two cases of acrodermatitis chronica atrophicans associated with Borrelia burgdorferi infection are reported; to our knowledge these are the first cases reported in children.

[Are psycho-organically disordered children inconspicuous as adults? A follow-up study of 125 probands].

ADD is very well known in english speaking countries (DSM III 26-29). At first american authors have demonstrated that psycho-organic disturbances do not disappear in all cases of adulthood. Attention deficit disorders, lack of concentration, weak short time memory, word finding difficulties, visuo-motor function deficiency, lability of mood, impulsivity, lack of self-control will often be found in adults. A defective ego-function seems to be the central disorder. These patients often grow up to pathologic personalities with a propensity to neurosis, addiction, various types of psychosis, namely to schizophrenia. With consideration to the heterogeneity of ADD, MDD hyperkinetic syndrome, psycho-organic syndrome etc. accurate follow-up studies are necessary for a better delineation on this nosological concept. Therefore we have investigated the development of 78 psycho-organic patients of our out-patient department. The first examination was made at the age of 10 years and the second ten years later. We obtained the following results: 1/3 of all patients were free of mental symptoms at the main age of 23 years. 1/2 presented slight symptoms in the cognitive field and/or in the emotional life, but vocational training and social adjustment were not impaired. 1/6 of the patients showed no improvement. They had remained in their family, still need care and help and were unable to accomplish professional training. These findings were compared with those of two groups of healthy persons (20 recruits of the swiss army and 27 female students of a nursing school). The differences were statistically significant in several dimensions.
