Source-derived summary

A mental disorder is an impairment of the mind disrupting normal thinking, feeling, mood, behavior, or social interactions, and accompanied by significant distress or dysfunction. The causes of mental disorders are very complex and vary depending on the particular disorder and the individual. Although the causes of most mental disorders are not fully understood, researchers have identified a variety of biological, psychological, and environmental factors that can contribute to the development or progression of mental disorders. Most mental disorders result from a combination of several different factors rather than just a single factor.

Risk factors

Risk factors for mental illness include psychological trauma, adverse childhood experiences, genetic predisposition, and personality traits. Correlations between mental disorders and substance use are also found to have a two way relationship, in that substance use can lead to the development of mental disorders and having mental disorders can lead to substance use/abuse. This effect is stronger and more reliable in some substance use than others, such as smoking.

Mental illnesses have risk factors including unequal parental treatment, adverse life events and drug use in depression, migration and discrimination, childhood trauma, loss or separation in families, cannabis use in schizophrenia and psychosis, parenting factors, child abuse, family history (e.g. of anxiety), temperament and attitudes (e.g. pessimism) in anxiety.

Editorial summary

This brief starts where responsible research should: with the source description of “Causes of mental disorders” as impairment of the mind causing disruption in normal thinking, feeling, mood, behavior, or social interactions, and accompanied by significant distress or dysfunction. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewA dependable orientation record for establishing vocabulary, names and a first evidence trail. The current 213-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. The account is most persuasive where Causes, mental and disorders can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as impairment of the mind causing disruption in normal thinking, feeling, mood, behavior, or social interactions, and accompanied by significant distress or dysfunction. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Aug 27, 2026. The linked authority identifier is Q5054620. None of the 0 selected statements returned an explicit reference.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
