ABSTRACT
Brain SPECT imaging (BSI) with statistical parametric mapping (SPM) offers a clear and accurate vision of perfusion changes.

OBJECTIVE:

To study brain perfusion abnormalities in adolescents' dependent of multiple drugs.

METHOD:

Sixteen male patients (15.1±2.1 years) were submitted to 99mTc-HMPAO BSI with SPM.

RESULTS:

Cortical hypoperfusion occurred in 7/16 patients (44 percent). There was a significant inverse correlation between the number of hypoperfused regions and the patient's age (p= -0.6737; p=0.004) and with the age when the drug dependence began (p= -0.5616; p=0.023). There was also a tendency towards an inverse correlation between regions of hypoperfusion and the duration of the drug dependence.

CONCLUSION:

BSI with SPM can help detect hypoperfusion in adolescents dependent on multiple drugs. The younger the patients, the more regions of hypoperfusion are noted. Probably, the neuronal plasticity has an important role in this phenomenon because the highest neural activity occurs in childhood.
RESUMO
SPECT cerebral (SC) com statistical parametric mapping (SPM) oferece uma visão clara e acurada de alterações perfusionais.

OBJETIVO:

Avaliar anormalidades perfusionais cerebrais em adolescentes usuários de múltiplas drogas.

MÉTODO:

Dezesseis pacientes masculinos (15,1±2,1 anos) foram submetidos a SC com SPM utilizando-se HMPAO-99mTc.

RESULTADOS:

Hipoperfusão cortical ocorreu em 7/16 pacientes (44 por cento). Houve uma significativa correlação inversa entre o número de áreas hipoperfundidas e a idade dos pacientes (p= -0,6737; p=0,004) e com a idade quando iniciaram o abuso das drogas (p= -0,5616; p=0,023). Também houve uma tendência para uma correlação inversa entre as áreas de hipoperfusão e a duração do abuso de drogas.

CONCLUSÃO:

SC com SPM pode auxiliar na detecção de hipoperfusão cortical em adolescentes dependentes de múltiplas drogas. Quanto menor a idade, mais áreas de hipoperfusão são identificadas. Provavelmente a plasticidade neuronal tem importante papel neste fenômeno, pois a maior atividade neuronal ocorre na infância.
