Personality disorders are persistent and deep-rooted disturbances in behaviour, perception and thinking that negatively affect a person’s personal and social life. DocuMental Clinic offers diagnosis and treatment via video consultation across Estonia, particularly in Tallinn and Tartu — no waiting list, no need to travel. Consultations are conducted by our specialist psychiatrists.

General Symptoms of Personality Disorders

  • inability to adapt flexibly in social situations
  • persistent patterns of perceiving oneself and others that differ from the norm
  • difficulties with emotional regulation — outbursts of anger, low mood, anxiety
  • impaired interpersonal relationships — lack of empathy or excessive dependency

Classification of Personality Disorders

Cluster A — Eccentric disorders

  • Paranoid personality disorder: distrust, suspicion, tendency to interpret others’ actions as threatening
  • Schizoid personality disorder: emotional coldness, detachment, limited interest in social contact
  • Schizotypal personality disorder: odd thinking and behaviour patterns, discomfort in close relationships

Cluster B — Dramatic and emotional disorders

  • Antisocial personality disorder: disregard for others’ rights, aggression, impulsivity, lack of remorse
  • Borderline personality disorder: instability in emotions, self-image and relationships, fear of abandonment, self-harm
  • Histrionic personality disorder: attention-seeking behaviour, emotional dramatisation
  • Narcissistic personality disorder: grandiosity, need for admiration, lack of empathy

Cluster C — Anxious disorders

  • Avoidant personality disorder: fear of criticism and rejection, avoidance of social interaction
  • Dependent personality disorder: excessive need for care, difficulty making independent decisions
  • Obsessive-compulsive personality disorder: perfectionism, excessive caution, need for control

Risk Factors

  • Genetic predisposition: personality disorders in close relatives increase risk
  • Neurobiological factors: dysfunction in the amygdala and frontal lobes that regulate emotion and behaviour
  • Childhood trauma: abuse, neglect, loss of a loved one in childhood
  • Attachment difficulties: unstable attachment to parents in early life

Treatment of Personality Disorders

Psychotherapy

  • Cognitive behavioural therapy (CBT): identifying and changing destructive beliefs and behaviour
  • Dialectical behaviour therapy (DBT): particularly effective for borderline personality disorder — teaches emotion regulation and reduces impulsivity
  • Psychodynamic therapy: works with deep psychological conflicts and the causes of behaviour patterns
  • Group therapy: improves social skills and reduces feelings of isolation

Pharmacological treatment

  • Antidepressants: sertraline, fluoxetine — for anxiety and depression
  • Mood stabilisers: carbamazepine, lamotrigine — for emotional instability
  • Antipsychotics: risperidone, quetiapine — to reduce impulsivity and aggression

Frequently Asked Questions

Can a personality disorder be diagnosed online in Estonia?

Yes. Our psychiatrists conduct detailed clinical interviews via video call and use standardised diagnostic scales. Online consultation is particularly convenient for patients in Tallinn and Tartu who prefer not to travel.

Is a personality disorder a lifelong condition?

Not necessarily. Personality disorders are chronic conditions, but with long-term psychotherapy many patients achieve significant improvements in quality of life and social functioning. Dialectical behaviour therapy is particularly effective for borderline personality disorder.

How does a personality disorder differ from ordinary character traits?

A personality disorder is diagnosed when persistent patterns of behaviour and thinking cause significant distress or impair social and professional functioning. Individual character traits are not a disorder. Only a psychiatrist can make the diagnosis.
