Personality disorders represent the dominant background features in evolution of addictive behaviours. In psychiatric emergency units these kind of conducts are able to start or maintain psychopathological manifestations and behaviours which have at their limits manifest selfaggression and on others and the irreversible failure of vital organs.

We have evaluated these specific conditions considering the main premorbid personality dimensions in two groups of pacients on records of Psychiatric Clinique 2 from Tg. Mureş.

The agravant and/or pathoplastic role of personality disorders is confirmed, considering that it influents also – and sometime in a decisive way – the compliance and efficiency of therapeutic relation and of rehabilitation strategies.

The presence of a personality disorder proves itself to be also a predictive factor for the precocity of psychopathological manifestations which require emergency assistance as well as for the frequency and complexity of associations between them.
