title: [Neurologic aspects of HIV infections--follow-up of pediatric patients].
abstract: OBJECTIVE
  Before the widespread introduction of combined antiretroviral therapy (1995) complications from HIV and AIDS in the central nervous system had been reported in larger proportion in infants and children than in adults: 80-90% versus 60-70%. Particular clinical manifestations tend to occur at different stages during the evolution of HIV infection. The authors review the neurological aspects of HIV infection.
  
  
  METHODS
  First, a summary of the protocol of the neurological examinations and related experience is given. Then authors present the evaluation of neuro-psychological development, prevalence of neurological impairment and neuro-imaging of nine HIV infected children (seven boys, two girls) for the period of ten years (1991-2001). Three/ten children had vertically transmitted HIV six/nine were infected by a nosocomial route in their early childhood. Children were regularly followed up from the diagnosis of HIV. The median follow up time has been 79 month (range: 18-144 month). Four patients died during the study period. The neurological status, the motor and mental development were examined at three month intervals or monthly under one year of age. EEG was performed every six month and CT/MRI once a year. All patients received combined antiretroviral treatment and immunoglobulin therapy continuously.
  
  
  RESULTS
  Three/nine children have normal development, one/nine has hyperactive and attention deficit disorder with normal IQ range, two/nine have slight, one/nine moderate and two/nine serious mental retardation. Mild neurological signs were found in two children, various moderate and serious neuro/psychological symptoms were found in four patients, one of them was treated with benign epilepsy too. There was also dose correlation between the clinical symptoms and the results of EEG examination (diffuse background slowing) and results of neuroimaging studies (cortical atrophy, calcification of the basal ganglia, toxoplasma abscesses). According to the results of different examinations three/nine children were found to be symptom-free, one/nine case showed the static form, two/nine patients showed the plateau form, two/nine the rapid progressive form and one/nine the progressive infantile form of AIDS encephalopathy. The majority of the patients suffered from adopting problems and difficulties of socialisation since their families lives were damaged by isolation and rejection from the community.
  
  
  CONCLUSIONS
  The regular neurological and psychological examinations completed with EEG, CT/MRI were very informative to follow the course of neuro-psychological problems of HIV infected children. Symptom-free patients have to face psychosocial problems too, which cause much more damage in their mental progress than HIV itself.
