Onychotillomania is a compulsive behavior characterized by an irresistible urge to pick at, pull off, bite, or chew one's nails. It is often associated with underlying psychiatric disorders such as depressive neurosis, delusions of infestation, or hypochondriasis. While it may not be a requirement for all psychiatric patients to cut their nails, those exhibiting onychotillomania may benefit from keeping their nails trimmed or finding alternative solutions to prevent self-harm and potential infections. This condition can lead to nail bed destruction, onychodystrophy, paronychia, and nail darkening, causing physical discomfort and requiring medical attention. Proper diagnosis and management of underlying mental disorders are crucial for comprehensive patient care.

Onychotillomania: a compulsive behaviour where patients pick, pull off, bite, or chew their nails
Onychotillomania is a compulsive behaviour where patients have an irresistible urge to pick at, pull off, bite, or chew their nails. It is distinct from onychophagia, which is self-induced nail damage caused by nail-biting or chewing, and dermatillomania, where skin is bitten or scratched. Onychotillomania can be categorised as a body-focused repetitive behaviour in the DSM-5 and is considered a form of skin picking or excoriation disorder.
The condition was named by Jan Alkiewicz, a Polish dermatologist, and can lead to several nail-related issues, including onychodystrophy, paronychia, and darkening of the nail. It is often associated with underlying psychiatric disorders, such as depressive neurosis, delusions of infestation, and hypochondriasis. In some cases, patients with onychotillomania may also experience more general symptoms of depression, including sleep and appetite disturbances, lack of interest, fatigue, and suicidal ideation.
The constant destruction of the nail bed caused by onychotillomania can result in physical complications. For example, one case study reported observing hemorrhagic, red-coloured crusts over all fingertips, with varied destruction of nail plates on the hands and toes. Other symptoms included multiple fissures and cuts on the fingertips and ulcers on the oral mucosa. Therefore, a comprehensive assessment, including a mental state examination, is essential for an accurate diagnosis and to rule out any other serious medical conditions or comorbid psychodermatological issues that may be causing pain or discomfort.
While the incidence of onychotillomania is thought to be relatively low and underreported, it can be successfully treated with antipsychotics or cheap solutions such as covering the proximal nail fold with cyanoacrylate glue.

Differentiating onychotillomania from onychophagia and dermatillomania
Onychotillomania, onychophagia, and dermatillomania are distinct conditions that involve compulsive behaviours related to the nails and skin.
Onychotillomania is characterised by a compulsion to pick at or tear off one's nails. It is a form of body-focused repetitive behaviour (BFRB) and is categorised as a type of skin-picking disorder, also known as excoriation disorder. This condition can lead to physical nail damage, such as onychodystrophy, paronychia, and darkening of the nail. It is often associated with psychiatric disorders such as depressive neurosis, delusions of infestation, and hypochondriasis.
In contrast, onychophagia is specifically the habit of nail-biting or nail-chewing. It is also classified as a BFRB and can result in similar physical nail damage as onychotillomania, including the potential for irreversible nail plate shortening. Onychophagia may be easier to diagnose clinically as it does not typically require histopathological analysis unless other diagnoses are being considered.
Dermatillomania, also known as excoriation disorder or skin-picking disorder, involves the compulsive picking of one's skin. Individuals with this condition may use their fingers, fingernails, teeth, or tools such as tweezers to pick at their skin. While most people pick at their skin occasionally, dermatillomania is characterised by an inability to stop the behaviour. This condition can also have negative physical consequences, such as skin lesions and infections.
Differentiating these conditions is important for accurate diagnosis and treatment. Onychotillomania and onychophagia specifically involve behaviours targeting the nails, while dermatillomania primarily involves skin-picking behaviours. Accurate diagnosis requires a detailed patient history and physical examination, as patients may feel embarrassed or hesitant to disclose these behaviours.

Psychiatric disorders associated with onychotillomania: depressive neurosis, delusions, hypochondriasis
Onychotillomania is a compulsive behaviour where a person constantly picks at their nails or tries to tear them off. This can be done using different tools such as scissors or toothpicks. It is distinct from onychophagia, which involves nail-biting, and dermatillomania, where skin is bitten or scratched. Onychotillomania can be associated with various psychiatric disorders, including depressive neurosis, delusions, and hypochondriasis.
Depressive Neurosis: Onychotillomania has been observed to co-occur with depressive episodes. In one case report, a 60-year-old man with recurrent depressive disorder exhibited onychotillomania during his depressive episodes. He experienced thoughts of suicide and had been hospitalised multiple times for his condition. The coexistence of onychotillomania and depression suggests a potential link between the two disorders.
Delusions: Onychotillomania has also been associated with delusional disorders. In some cases, the nail-picking behaviour may be motivated by delusions or occur alongside psychotic symptoms such as auditory hallucinations. Delusions of infestation are commonly reported in individuals with onychotillomania, reinforcing the connection between this behaviour and delusional thinking.
Hypochondriasis: Hypochondriasis, or excessive worry about one's health, has also been linked to onychotillomania. Individuals with hypochondriasis may exhibit onychotillomania as a form of body-focused repetitive behaviour. This can lead to self-destructive habits that further impact their mental and physical health.
The relationship between onychotillomania and these psychiatric disorders highlights the importance of comprehensive mental health evaluations. By recognising the underlying mental health disorders associated with onychotillomania, healthcare professionals can provide appropriate treatment and support to individuals experiencing these co-occurring conditions.

Treatment options for onychotillomania: antipsychotics, Cyanoacrylate glue
Onychotillomania, or repetitive nail picking and pulling, is a chronic nail condition. It is categorised as a body-focused repetitive behaviour (BFRB) disorder and can cause physical and psychosocial harm to the individual. Treatment options are varied and often involve both pharmacological and non-pharmacological approaches.
Antipsychotics
Onychotillomania can be associated with psychiatric disorders such as depressive neurosis, delusions of infestation, and hypochondriasis. As such, antipsychotics have been used to treat the condition with some success. However, patients with comorbid psychiatric illnesses such as depression, OCD, or psychosis have also been treated with psychotropic drugs, including SSRIs, TCAs, and typical antipsychotics. In one case, a patient with onychotillomania and coexisting depression was treated with sertraline (150 mg/day). After four weeks, depressive symptoms improved, and nail picking decreased, with both conditions resolving after six weeks.
Cyanoacrylate Glue
Applying a fast-drying cyanoacrylate glue, such as Super Glue or Krazy Glue, to the proximal nail fold once or twice a week is an inexpensive and effective treatment for onychotillomania. The glue creates a physical barrier that protects the nail fold, and it can also serve as a reminder to stop picking. In a case report, two patients using this method ceased nail picking within three to six months and achieved normal-appearing nails. However, one potential hazard of long-term use is the development of allergic contact dermatitis to the acrylate.
Other treatment options for onychotillomania include non-pharmacological approaches such as band-aids and occlusive dressings, although patients may find these socially unacceptable or burdensome. Cognitive-behavioural therapy (CBT) may also be beneficial, as it can increase awareness of nail-picking behaviours and has been used successfully to treat other BFRBs.

The importance of thorough mental state examinations for accurate diagnosis
While there is no explicit requirement for psychiatric patients to cut their nails, the presence of certain psychiatric disorders can manifest in nail-related behaviours. Onychotillomania, for instance, is a compulsive behaviour characterised by an irresistible urge to pick at, pull off, bite, or chew one's nails. This condition is distinct from onychophagia, which is nail-biting without the compulsion to pick or pull, and dermatillomania, which involves biting or scratching the skin.
Onychotillomania is often associated with underlying psychiatric disorders such as depressive neurosis, delusions of infestation, and hypochondriasis. A thorough mental state examination is crucial for an accurate diagnosis of these comorbid conditions. For instance, a patient presenting with onychotillomania may, upon examination, reveal symptoms indicative of a severe depressive episode, such as disturbances in sleep and appetite, lack of interest, fatigability, and suicidal ideation.
Comprehensive mental state examinations enable the identification of serious medical conditions and comorbid psychodermatological problems that may otherwise go unnoticed. In the case of onychotillomania, a psychiatric evaluation may uncover underlying depressive disorders that require separate diagnosis and treatment. This two-pronged approach ensures that the patient receives appropriate care for both their dermatological and psychiatric concerns, improving overall patient outcomes.
The importance of thorough mental state examinations extends beyond onychotillomania and dermatological presentations. Mental state examinations are integral to the accurate diagnosis of a wide range of psychiatric disorders. They allow clinicians to assess a patient's mood, thoughts, perceptions, cognition, insight, and judgement, all of which are critical to formulating a treatment plan. By taking a comprehensive patient history and conducting a detailed mental state examination, clinicians can make more informed decisions, rule out potential differential diagnoses, and personalise treatment approaches.
In conclusion, the case studies of onychotillomania highlight the critical role of thorough mental state examinations in ensuring accurate diagnosis and comprehensive patient care. While nail-related behaviours may initially present as the primary concern, a detailed examination can uncover underlying psychiatric disorders that require separate attention. This underscores the importance of addressing the complex interplay between physical and mental health, ensuring that patients receive holistic care that addresses all aspects of their wellbeing.

Frequently asked questions
There is no specific requirement for psych patients to cut their nails. However, some patients may suffer from onychotillomania, a compulsive behaviour where a person picks at, pulls off, or bites their nails constantly. This can lead to destruction of the nail bed and other nail problems. In such cases, keeping nails short might be recommended to reduce the surface area available for destructive behaviours.
Onychotillomania can be treated with antipsychotics. A cheap solution suggested by researchers is to cover the proximal nail fold with a Cyanoacrylate glue. Thorough mental state examinations are essential for a comprehensive assessment of the patient's problems and underlying mental disorders.
Onychophagia is self-induced nail damage caused by nail-biting or chewing. It does not involve picking or tearing at the nails as seen in onychotillomania.
