1. A method for predicting one or more neurological disorders via a processor configured to execute program instructions stored in a memory, the method comprising: receiving, via the processor, one or more videos of one or more individuals; splitting, via the processor, the one or more videos into one or more frames; detecting, via the processor, one or more regions of interest in each of the one or more frames; analyzing, via the processor, each of the one or more regions of interest in each of the one or more frames by: determining a motion vector for each of the one or more regions of interest in a set of successive frames; and comparing value of the determined motion vector for each of the one or more regions of interest with corresponding pre-stored values, wherein the pre-stored values for the motion vector for each of the one or more regions are pre-stored in a database; identifying, via the processor, at least one motion vector, from the determined motion vectors, that matches with a pre-stored value of a motion vector thereby identifying a region of interest and a frame corresponding to the identified at least one motion vector, wherein the pre-stored value indicates onset of an expression; determining, via the processor, one or more motion vectors for the identified region of interest in subsequent sets of successive frames; comparing, via the processor, value of the one or more determined motion vectors for the identified region of interest with at least one of a pre-stored value of motion vector corresponding to peak of an indicated expression and a pre-stored value of motion vector corresponding to offset of the indicated expression, wherein the peak of the indicated expression and the offset of the indicated expression are values in at least one of a graph, a histogram and a table depicting the indicated expression; identifying, via the processor, the frame corresponding to the at least one of: the peak of the indicated expression and the offset of the indicated expression; and generating, via the processor, a pictorial representation of the one or more videos depicting at least one of: the onset, peak and offset of the indicated expression of the one or more individuals captured in the one or more videos for predicting the one or more neurological disorders.
