Introduction

Munchausen Syndrome (MS), also known as Factitious Disorder, is a condition in which a person intentionally fabricates symptoms of illness to receive attention or care, leading to unnecessary medical investigations and spending. It is regarded as a mental disorder defined by pathological lying, aimless wandering, and malingering to gain sympathy. It was first described by Richard Asher in 1951 as a mental disorder.According to The Diagnostic and Statistical Manual of Mental Disorders (DSM-5 ), factitious disorder is of 2 types:

1. Imposed on self: a circumstance in which someone claims to be unwell or injured.

Bruising as a result of factitious disorder imposed on the self

2. Imposed on another: also called Munchausen syndrome by proxy in which a victim, frequently a child, is depicted as being sick, disabled, or injured by someone else, who could be a carer or parent..DSM-5.

Clinical presentation

• Physical Symptoms: self-inflicted symptoms such as pain, fever, convulsion
• Psychological Symptoms: display of anxiety, psychosis, depression, suicidal thoughts, or personality disorder.
• Frequent Hospital Visits: frequent hospitalizations with inconsistencies in medical history and clinical investigations.

Aetiology

The causes of Munchausen syndrome are complex and not fully understood. Research suggests that factors such as childhood abuse, early loss of a loved one, feelings of neglect, unmet emotional needs during childhood, and low self-esteem may contribute to the development of this disorder.

Diagnosis

There is no specific diagnostic test for this condition, a clinician must act as a detector to identify any falsehood reports by the patient. Hence, a detailed medical history and physical examination are crucial in the diagnosis. The following steps can be followed in the diagnostic process

1. Identify inconsistencies in patient presentations and clinical findings.
2. Exclude major differential diagnosis.
3. Gather enough evidence that may indicate that their account is misleading.
4. Identify any evidence of deception.
5. Confirm every piece of evidence gathered by seeking the opinions of other colleagues.

Several indicators that may aid diagnosis include:

1. Results of Inconsistent Examinations that don't match the patient's stated symptoms.
2. Several Tests Without a Definite Diagnosis.
3. Complex Medical History with numerous ailments.
4. Reluctance to Provide medical history may be a source of concern.
5. inconsistencies between what the patient stated and their documented medical history.
6. Exaggerated symptoms that do not correspond with the anticipated diagnosis.

Differential Diagnosis

• Psychiatry disorder
• Conversion disorder also called Functional Neurological Disorder (FND)
• Malingering
• Delusional Disorder
• Somatic Symptom Disorder
• Depression
• Substance Use Disorder
• Personality Disorder

Management

According to the currently available evidence, the use of medications has not shown significant alleviation of Munchausen syndrome. Also, confrontation with patients suspected to have this disorder has led to not admitting the condition, therefore, a more supportive and empathetic approach is advised. The only effective treatment currently available for this disorder is Psychotherapy. The treatment of psychiatry comorbidities such as depressive disorders associated with MS may indirectly improve symptoms. Experts have suggested a multidisciplinary approach involving nurses, therapists, primary care physicians, psychiatrists, and family members.

Physiotherapy Management

Physiotherapy can be very helpful in treating patients who have Munchausen's Syndrome. Physiotherapists can offer supportive care that manages physical symptoms and enhances general well-being, even though they do not directly treat the underlying psychological problems.

1. Evaluation and Assessment: To differentiate between fictitious and actual physical conditions, a thorough evaluation is necessary. Physiotherapists should complete detailed physical examinations, functional assessments, and a review of the patient's medical history. This checks out for potential deception and aids in identifying valid impairments.
2. Multidisciplinary approach: Psychologists, psychiatrists, and other medical professionals must frequently collaborate to treat Munchausen syndrome effectively. Physiotherapists should collaborate with other health professionals in a multidisciplinary framework to address both psychological support and physical rehabilitation.
3. Creating trustworthy connections: when assisting individuals with Munchausen syndrome, physiotherapists should build trust with the patient through treatment with empathy and a non-judgmental approach as this can help patients to be open and honest about their symptoms.
4. Physical Rehabilitation Techniques: if there is an indication of true physical limitations and discomfort after evaluation, the physiotherapist should formulate an exercise plan tailored towards the patient's needs.
5. Self-management techniques and education: Patient education is a key component of physiotherapy management. Educating patients about their condition can help them develop coping skills for stress or anxiety that might be influencing their actions.
6. Progress Monitoring: Patient monitoring and frequent check-ups can be useful in evaluating behavioural changes or symptom reporting as this can drive modification of treatment plans.
