Niveles elevados del aminoácido se han relacionado en estudios anteriores con un mayor riesgo de enfermedad cardiovascular, de atrofia cerebral y de enfermedad de Alzheimer.
En el presente estudio, los autores examinaron la relación entre la homocisteína y diversos hallazgos en imágenes del cerebro obtenidas mediante resonancia magnética en individuos de 60 a 64 años. Participaron en la investigación 196 varones y 189 mujeres, que también fueron sometidos a diversos tests para evaluar su función cognitiva.
Los resultados muestran que no se encontró una relación entre los niveles del aminoácido y la atrofia cerebral, pero sí con cambios en la hiperintensidad de la materia blanca profunda, observado con la resonancia magnética, cambios que pueden ser relevantes en forma de deterioro cognitivo leve.
