Australian psychologist Marny Lishman explains how to recognise a sociopath
She says a standard trait of a sociopath is that they are charming and gregarious
Dr Lishman advises while they appear functional, they can act without remorse
She outlines a list of behaviours that can be common to those with this disorder
Many people use the word 'sociopath' flippantly to describe people they dislike, but few understand what the term really means.
In actual fact, most 'sociopaths' have a form of antisocial personality disorder (APD) and as a result have zero disregard for what is right and wrong and rarely care about the feelings of others.
Research has found that one in every 25 people has the traits of a sociopath so it's entirely possible that you could be dating one and have no idea - especially as they are often charming and highly charismatic.
Australian psychologist Dr Marny Lishman recently spoke to FEMAIL about the tell-tale signs of a sociopath and what you should know if you're dating someone with APD.
