Alongside this are cognitive disturbances where individuals contend with over-valued ideas of being bad. Patients with BPD assign invalidation from others from benign looks or comments that other people may not have even noticed. These looks or comments are seen by the patient as ”Recognition from others of the badness within them”. Depersonalisation and derealisation with non-delusional suspiciousness and an overvalued idea that normal occurrences are somehow connected to them are also features. Men sometimes report quasi psychotic phenomena, such as reality- based delusions and hallucinations.
Men diagnosed with Borderline Personality Disorder have been recognised to be prone to impulsivity. This is evidenced through self-damaging behaviours. These may be combined with substance misuse, financial mismanagement and verbal outbursts.
