Abuse

by S. Serkan Sezer MD

The word abuse is one of the most encompassing and serious terms in medical and social science literature. It covers a wide spectrum — from misuse of a substance to harmful treatment of a person — and is encountered across psychiatry, paediatrics, addiction medicine, forensic medicine, and public health.

Definition

In English medical dictionaries, the word is given as a noun (transcribed /əˈbjuːs/) and as a verb (transcribed /əˈbjuːz/), with several distinct meanings:

As a noun:

  1. The wrongful use of something — for example, the abuse of a privilege.
  2. The illegal use of a drug or the overuse of alcohol — for example, substance abuse.
  3. The same as child abuse.
  4. The bad treatment of a person — for example, physical abuse or sexual abuse.

As a verb:

  1. To use something wrongly — for example, Heroin and cocaine are drugs which are commonly abused. The expression to abuse one’s authority refers to using one’s powers in an unlawful or harmful way.
  2. To treat someone badly — for example, sexually abused children or He had physically abused his wife and child.

The common thread running through all these meanings is the same: the wrongful, harmful, or improper use of a thing, a right, or a person.

Types of Abuse

In clinical and social settings, several main categories of abuse are recognised:

1. Substance Abuse

The harmful or hazardous use of alcohol, illicit drugs, or prescription medicines. It includes:

  • Alcohol abuse — drinking that exceeds safe limits and produces health, social, or occupational harm.
  • Drug abuse — non-medical use of illicit substances such as heroin, cocaine, cannabis, or amphetamines.
  • Prescription drug abuse — using prescribed medications (opioid analgesics, benzodiazepines, stimulants, etc.) outside medical indications or in excessive doses.
  • Inhalant abuse — inhaling volatile substances such as solvents and glues.

In current diagnostic classifications, this area is now generally referred to as substance use disorder.

2. Child Abuse

Any harmful behaviour directed by an adult towards a child. It takes several forms:

  • Physical abuse — beating, kicking, burning, shaking, and other physical injury.
  • Sexual abuse — any form of sexual contact with, or sexual exposure of, a child.
  • Emotional / psychological abuse — constant criticism, humiliation, threats, and rejection.
  • Neglect — failure to provide for a child’s basic physical or emotional needs, such as nutrition, healthcare, education, or affection.

3. Domestic Abuse

Harmful behaviour by one family member towards another, including:

  • Physical violence — hitting, pushing, and other physical assault.
  • Sexual violence — non-consensual sexual contact.
  • Emotional abuse — verbal aggression, threats, and humiliation.
  • Economic abuse — controlling finances and limiting economic independence.
  • Coercive control — isolating, monitoring, and restricting a partner’s freedom.

4. Elder Abuse

Harm directed at older adults. It can occur in the family, in care facilities, or in healthcare settings. Forms include physical, emotional, sexual, financial, and neglect-based abuse.

5. Abuse of Power and Authority

The misuse of an official, professional, or social position for personal gain or to harm others — for example, breaches of the doctor–patient relationship, workplace harassment, or political corruption.

Clinical Assessment

For healthcare professionals, recognising abuse is critically important. Warning signs may include:

  • Physical findings — unexplained bruises, burns, fractures of different ages, injuries inconsistent with the history given.
  • Behavioural changes — anxiety, depression, sleep disturbance, social withdrawal, sudden changes in personality.
  • Developmental signs — in children, growth retardation, language delay, regression in toilet training or other skills.
  • Inconsistencies in history — the explanation of an injury changing over time or being incompatible with the findings.
  • Frequent emergency visits — repeated attendances with different or vague complaints.

Health Consequences

Abuse — in any form — produces both short- and long-term harm:

Physical Effects

  • Acute injuries: bruises, fractures, burns, head trauma
  • Chronic pain
  • Genital and reproductive tract injuries
  • Pregnancy complications
  • In severe cases, permanent disability or death

Psychological Effects

  • Post-traumatic stress disorder (PTSD)
  • Depression and anxiety disorders
  • Suicidal thoughts and behaviour
  • Self-harm
  • Eating disorders
  • Sleep disorders
  • Substance use disorders

Social Consequences

  • Difficulties forming and maintaining relationships
  • Reduced academic and occupational performance
  • Social isolation
  • Increased risk of becoming an abuser or being abused in adulthood (intergenerational cycle)

Response and Intervention

The approach to suspected or confirmed abuse rests on several pillars:

  • Recognition — health professionals being alert and able to identify warning signs.
  • Safety — the immediate priority is to ensure that the victim is no longer at risk of further harm.
  • Medical assessment and treatment — care of injuries and treatment of any associated medical and psychological consequences.
  • Documentation — careful recording of findings, important for both medical and legal purposes.
  • Reporting — in many countries, healthcare professionals are legally required to report child abuse, elder abuse, and certain forms of domestic abuse.
  • Multidisciplinary support — collaboration between physicians, psychologists, social workers, police, and legal services.
  • Long-term follow-up — psychotherapy, support groups, and social services.

Prevention

Tackling abuse requires effort not only after it has occurred but also through prevention:

  • Education — public-information campaigns and school-based programmes.
  • Family support — parenting programmes and stress-management resources.
  • Substance-use prevention — programmes targeting alcohol and drug misuse.
  • Legal regulation — strong laws protecting children, women, and older adults.
  • Healthcare screening — incorporating questions about abuse into routine medical care.
  • Community awareness — encouraging people to recognise and report abuse.

Help and Support

People who are experiencing abuse should know that they are not alone and that help is available. Many countries operate:

  • Helplines for victims of domestic violence
  • Child protection services
  • Sexual assault crisis centres
  • Treatment services for substance use disorders
  • Psychological support and counselling services

Healthcare professionals are an important point of contact, and the doctor–patient relationship is confidential.
