Surgery and Radiosurgery in Autism: A Retrospective Study in 10 Patients.

Introduction: A subgroup of patients with autism spectrum disorder (ASD) show self or heteroaggression, dyscontrol episodes, and others are of obsessive-compulsive disorder (OCD) profile; some of them are resistant to medical and behavioural treatment. We describe the long-term outcome in a group of these patients, treated with radiofrequency brain lesions or combined stereotactic surgery and Gamma Knife (GK) radiosurgery.

Methods: We reviewed the medical records of 10 ASD patients with pathological aggressiveness and OCD, who had undergone radiofrequency lesions and/or radiosurgery with GK in our institution.

[Neuropsychology of Korsakoff's syndrome].

The main manifestation of Korsakoff's syndrome is a disproportionate impairment in memory in comparison to other cognitive functions. Most prominent is anterograde amnesia for both verbal and nonverbal information. The marked sensitivity to interference is the main characteristic of memory impairment of these patients.

[Memory disorders and attention deficit modulation in child hyperactivity].

The infantile hyperactivity is a disorder of great significance due to its remarkable after-effects on the family, the school and the individual. According to strict diagnostic criteria the study of the memory in these children who present a well defined disorder of the attention, has been planned. The data show that the mnemonic capacity is primarily kept.

[Brain mapping studies in dyslexia].

Brain EEG mapping has been recorded during three different conditions, rest closed eyes, rest open eyes, and reading task, in a group of 22 dyslexic children, age mean 9.3 years, range 8-11, and control group of normal readers of the same age. All the subjects were right-handed, and laterality was assessed through the Edinburgh test.

[Neurophysiologic bases and neuropsychological approach to the study of infantile hyperactivity].

Hyperactivity is a common important group of childhood behaviour problems with great influence on the personal, familiar and social sphere, a better knowledge of which is important. Up to now several explanatory hypotheses have been pointed out. From some time ago, the physiopathological roots of this clinical description has been studied in depth.
