<unk> , also known as<unk>  disorder is a clinically recognised mental health condition (ICD-11, 2018). The disorder is characterised by accumulation of possessions due to excessive acquisition of or difficulty discarding possessions, regardless of their actual value. Excessive acquisition is characterized by repetitive urges or behaviours related to amassing or buying items. Difficulty discarding possessions is characterized by a perceived need to save items and distress associated with discarding them. Accumulation of possessions results in living spaces becoming cluttered to the point that their use or safety is compromised. The symptoms result in significant distress or significant impairment in personal, family, social, educational, occupational or other important areas of functioning. Prevalence rates are estimated at 2% to 5% in adults, though the condition typically manifests in childhood with symptoms worsening in advanced age, at which point collected items have grown excessive and family members who would otherwise help to maintain and control the levels of clutter have either died or moved away. People with<unk>  disorder commonly live with other complex and/or psychological disorders such as depression, anxiety and attention deficit hyperactivity disorder (ADHD). Other factors often associated with<unk>  include alcohol dependence and paranoid, schizotypal and avoidance traits.
