Abstract

MéTODO E UM SISTEMA PARA AVALIAR CONDIçõES NEUROLOGICAS. A presente invenção refere-se a um método e um sistema para gerar um sinal discriminatório para uma condição neurológica, onde pelo menos um composto de sonda que tem um efeito neurofisiológico é fornecido. Dados de biossinal são obtidos de um paciente com base em medições de biossinal obtidas a partir do dispositivo de medição de biossinal adaptado para a colocação em um paciente, em que os ditos dados de biossinal são obtidos posterior à administração do dito composto de sonda ao paciente. Dados de referência de biossinal análogos são fornecidos para pacientes de referência em pelo menos um grupo de referência posterior à administração do composto de sonda, em que os dados de referência são utilizados para definir características de referência tendo características comuns entre os pacientes de referência em o pelo menos um grupo de referência, em que os dados de referência são processados para definir vetores de probabilidade a priori de referência para cada paciente de referência respectivo, em que cada vetor de probabilidade a priori respectivo compreende característica particular ou uma combinação de características de elementos com valores de probabilidade associados aos ditos elementos, os vetores de probabilidade a priori resultando em uma distribuição das ditas características ou combinações de características para os ditos pacientes de referência. Subseqúentemente, os dados de biossinal obtidos do paciente são usados para calcular o vetor de probabilidade a priori análogo para o dito paciente. O sinal discriminatório depois é gerado com base na comparação entre o dito vetor de probabilidade a priori para o dito paciente e a distribuição das ditas características ou combinações de características.
