An important kind of medical research is clinical research, which addresses the essential questions of normal function and disease using human subjects. Clinical research is carried out with patients. It is generally supervised by doctors in a medical setting such as a hospital and requires ethical approval.
Other kinds of medical research include pre-clinical research, for example, on animal and basic medical research, for example, in genetics.
Clinical Research Examples
Autism, also referred to as autism spectrum disorder (ASD), is now widely viewed as being of developmental neurological origin.
It constitutes neuro-developmental disorder characterized by impairment in communication, including language, social skills, and comportment, often involving rigidity of interests and repetitive, stereotypical behaviors.
The incidence of autism appears to be increasing. It is evident from representative studies that neuro-anatomical and neurophysiological abnormalities, as well as significant co-morbid mental illness, exist among the children with autism.
Sharing the clinical experience with related professionals, Mullick, and his colleagues (Mullick et al., 2013) also developed similar impressions and intended to explore these issues in Bangladesh.
Keeping the problems in view, the authors aimed at delineating the proportion of structural magnetic resonance imaging (MRI) abnormality among the children with autism and to assess any possible association and EEG with co-morbid mental illness.
The study was a cross-sectional descriptive study and clinical.
