Abbreviations used: PPD – Paranoid Personality Disorder, SzPD – Schizoid Personality Disorder, StPD – Schizotypal Personality Disorder, ASPD – Antisocial Personality Disorder, BPD – Borderline Personality Disorder, HPD – Histrionic Personality Disorder, NPD – Narcissistic Personality Disorder, AvPD – Avoidant Personality Disorder, DPD – Dependent Personality Disorder, OCPD – Obsessive–Compulsive Personality Disorder, PAPD – Passive–Aggressive Personality Disorder. The disorders in each of the three clusters may share with each other underlying common vulnerability factors involving cognition, affect and impulse control, and behavioral maintenance or inhibition, respectively. But they may also have a spectrum relationship to certain syndromal mental disorders:
Paranoid, schizoid or schizotypal personality disorders may be observed to be premorbid antecedents of delusional disorders or schizophrenia. Borderline personality disorder is seen in association with mood and anxiety disorders, with impulse-control disorders, eating disorders, ADHD, or a substance use disorder. Avoidant personality disorder is seen with social anxiety disorder. Impact on functioning
It is generally assumed that all personality disorders are linked to impaired functioning and a reduced quality of life (QoL) because that is a basic diagnostic requirement. But research shows that this may be true only for some types of personality disorder. In several studies, higher levels of disability and lower QoL were predicted by avoidant, dependent, schizoid, paranoid, schizotypal and antisocial personality disorders. This link is particularly strong for avoidant, schizotypal and borderline PD. However, obsessive–compulsive PD was not related to a reduced QoL or increased impairment.
Ocular rosacea is a manifestation of rosacea that affects the eyes and eyelids. Signs and symptoms generally consist of redness, irritation or burning of the eyes. Affected individuals may also feel that there is something, such as an eyelash, in the eye and frequently have redness of the nose and cheeks as well. Those who have ocular rosacea may be treated with warm compresses, artificial tears and washing the area around the eye with warm water, including the eyelids, to help relieve symptoms. Additionally, oral antibiotics, typically doxycycline, may be prescribed. Some people with ocular rosacea feel that dietary restrictions of caffeine, spicy foods, and alcoholic beverages may reduce or eliminate symptoms. Ocular rosacea may be caused by an overproliferation of the Demodex mites D. folliculorum and D. brevis, both frequently referred to as "eyelash mites". Notes
