There are two approaches used to classify<unk><unk> s; categorical and dimensional. Categorical classification is based on distinct operational criteria depending on behavioral characteristics. DSM-5 and ICD-10 both uses this approach. As compared to this, dimensional classification is based on the<unk>  traits and using a quantitative distinction. It places normality at one end and<unk>  at other. DSM-5 classifies 10<unk><unk> s into three clusters due to similar characteristics:
CLUSTER A is defined as odd and eccentric and include Paranoid, Schizoid, and Schizotypal. CLUSTER B is defined by erratic and emotional behavior and includes Antisocial, Borderline, Histrionic and Narcissist. CLUSTER C PDs patients are anxious and fearful and incorporate Avoidant, Dependent and Obsessive-Compulsive. ICD-10 classifies into 3 clusters as well, which are A, Odd/eccentric and includesParanoid and Schizoid, B, Dramatic and includes Dissocial, Emotionally unstable borderline type, Emotionally unstable impulsive type and Histrionic, and C, Anxious/fearful that include Anxious, Dependent and Anankastic.
