    Understanding Most Common Mental Disorders in Nursing

    As a student diving into the field of nursing, it's crucial for you to gain an understanding of common mental health disorders. This will enable you to provide comprehensive, empathetic care to a wide spectrum of patients, from all walks of life.

    In recent years, there has been a significant increase in mental health awareness, with more people seeking help for their mental health problems. This has led to an increase in the number of patients you might see in a healthcare setting who are affected by these conditions.

    Overview of the Most Common Mental Disorders

    An understanding of common mental disorders starts with grasping the basic concepts defining each condition.

    Common mental disorders represent a wide range of conditions that affect mood, thinking, and behaviour, which can significantly interfere with daily life. These disorders include depression, anxiety disorders, schizophrenia, eating disorders, addictive behaviours, and many others.

    It's important to get acquainted with the symptoms, causes, and treatment options of each.

    • Anxiety disorders: Characterized by excessive fear or anxiety. May include panic disorder or specific phobias.
    • Depressive disorders: Characterized by persistent feelings of sadness and loss of interest in activities. Major depression and dysthymia fall under this category.
    • Schizophrenia: A disorder that affects a person's ability to think, feel, and behave clearly. Marked by hallucinations, delusions, and thought disorders.
    • Eating Disorders: Characterized by abnormal eating habits that negatively affect a person's physical or mental health. Anorexia nervosa and bulimia nervosa are common examples.
    • Addictive disorders: Involves dependence on substances such as alcohol, drugs, or behaviours like gambling.

    Epidemiology: Prevalence of Common Disorders

    When studying nursing, it's equally important to understand the prevalence of common mental disorders. This helps you comprehend the scope and impact of these disorders on society.

    Below is a representation of the global prevalence of some common mental disorders according to the World Health Organization (WHO).

    DisorderGlobal Prevalence (\%)
    Anxiety disorders\(3.6\%\)
    Bipolar disorder\(0.6\%\)
    Alcohol use disorders\(1.3\%\)
    Drug use disorders\(0.4\%\)

    By understanding these statistics, you can better appreciate the need for competent, caring, and dedicated nurses in the mental health field. It is also a reminder of the ongoing and increasing need for education, research, and treatment in this area.

    Identifying and Diagnosing Common Disorders in Mental Health Nursing

    Mental health disorders encompass a wide diversity of conditions, each with specific symptoms, effects, and treatment necessities. For this reason, learning how to accurately recognise and diagnose these disorders is an essential skill for aspiring nurses.

    Common Disorders Symptoms and Recognising Them

    In order to recognise potential mental health disorders, you have to gain a nuanced understanding of the typical symptoms associated with each common disorder. It's also imperative to appreciate how these symptoms might manifest in various scenarios, as it's the presentation that often compels a patient to seek professional help.

    Symptoms are the physical or mental features that are regarded as indicating a condition of disease, particularly such a feature that is apparent to the patient.

    • Depression: Symptoms may include persistent feelings of sadness, lack of interest or pleasure in activities, feelings of worthlessness, sleep disturbances, loss of appetite, and suicidal ideation.
    • Anxiety disorders: These disorders are marked by excessive and enduring fear about everyday situations. Fast heart rate, rapid breathing, feeling nervous, and having an intoxicating sense of impending danger are common symptoms.
    • Schizophrenia: Common symptoms include hallucinations, delusions, thought disorders, and movement disorders. Screening for these symptoms needs care and sensitivity.
    • Eating disorders: Major symptoms to recognise include preoccupation with weight, body shape, eating, and food, severe restrictions on food intake, binge eating, and inappropriate compensatory behaviours such as forced vomiting.
    • Addictive disorders: Symptoms of substance addiction can include uncontrollable cravings and compulsive use of the substance despite knowing its harmful consequences.

    Recognising these symptoms is the first step in the identification of mental health disorders. It is important to clarify that only a qualified healthcare professional can conduct an accurate diagnosis. As a nurse, your role can be critical in identifying potential issues and referring them appropriately.

    Nursing Approaches for Diagnosis of Common Disorders

    The nursing diagnosis of mental health disorders can often be a complex process that involves comprehensive assessments and application of diagnostic standards.

    Here are some of the standard methods that you might use:

    • Brief screening tools: These can be highly useful in identifying possible symptoms of mental disorders. Tools like the General Health Questionnaire (GHQ) are commonplace in many healthcare settings.
    • Diagnostic interviews: When more definite diagnosis is needed, structured or semi-structured interviews can be invaluable, such as the Structured Clinical Interview for DSM (Diagnostic and Statistical Manual of Mental Disorders).
    • Observational methods: Some aspects of mental health disorders can best be identified through careful observation of a patient's behaviour, mood, and interactions.
    • Collateral information: Gathering information from family members or other significant people in the patient's life can provide a broader view of the patient's situation.

    For example, a patient may come to the nursing unit showing visible signs of extreme weight loss. They might avoid meals and express an intense fear of gaining weight. The nurse, by recognising these symptoms and using diagnostic tools and interview techniques, may begin suspecting an eating disorder. With collateral information from the patient's family confirming the patient's abnormal eating habits, the nurse can then refer the patient to a specialist for further examination and possible diagnosis.

    Remember, the most important role a nurse plays in mental health care is to observe and report, not diagnose. Your observations, considerations and recommendations can become crucial in forming an overall diagnosis by a qualified healthcare provider.

    Treatment and Management in Nursing of Common Disorders

    For healthcare professionals such as nurses, the treatment and management of common disorders require a holistic approach that places the patient at the centre of care. Comprehensive patient care not only encompasses medicinal treatments but also amounts to mental and emotional support.

    Nursing Management of Common Disorders

    Nursing management of mental health disorders often involves comprehensive care plans and intervention strategies, guided by appropriate models of mental health.

    Nursing management refers to the role of nurses as leaders in healthcare settings - overseeing care delivery while contributing to the wellbeing, recovery, and health promotion of patients.

    In managing common disorders such as depression, anxiety disorders, schizophrenia, eating disorders, and addictive behaviours, nursing strategies will differ based on the specific needs of the patient. However, some general strategies can include the following:

    • Educating the patient: Patients should be well-informed about their condition, treatment options, coping strategies, and prevention measures.
    • Psychotherapy: Supporting patient participation in therapies such as cognitive behavioural therapy (CBT), dialectical behaviour therapy (DBT), and interpersonal therapy (IPT).
    • Medication management: Ensuring the appropriate use of prescribed medications, managing side effects, and monitoring the patient’s response to the medication.
    • Group and family therapy: Encouraging participation in group therapies to foster social skills and reduce feelings of isolation. Family therapy can also strengthen familial relationships and support systems.
    • Community resources: Guiding the patient to connect with community resources such as support groups, vocational services, and more.

    Ultimately, the goal of nursing management is to help patients reach their highest level of functioning while reducing the impact of symptoms on their quality of life.

    Care Plans for Common Disorders: Models and Strategies

    While managing disorders entails similar strategies across the board, crafting individualised care plans necessitates viewing each patient as unique, with diverse needs and recovery pathways.

    A care plan is a thorough approach to patient care, often used in the health professions, which includes diagnosis, anticipated outcomes, interventions, and evaluation.

    To formulate effective care plans, nursing professionals often employ proven models and frameworks to guide their care delivery. Tidal Model, the Stress-Vulnerability Model, or the Self-Efficacy Theory are typical examples used in mental health nursing.

    Let's have a closer look at the components of a sample care plan for managing depression:

    Nursing DiagnosisRisk for suicide related to feelings of hopelessness and worthlessness
    Patient OutcomeThe patient will express feelings openly with healthcare providers and family members within one week.
    Interventions- Assess the patient for suicidal ideation regularly - Encourage verbalisation of feelings - Maintain a safe environment - Collaborate with mental health professionals for further evaluation
    EvaluationThe patient's progress will be continually evaluated against the expected outcome.

    These models and care plans support nurses in systematic and holistic patient care. By implementing a structured yet flexible approach based on these models, the therapeutic journey can be made smoother and more constructive for both the patient and caregiver.

    For example, if a nurse is assigned to a patient diagnosed with schizophrenia, a care plan based on the Stress-Vulnerability model might be employed. This model stipulates that schizophrenia results from genetic vulnerability and stress factors in the environment. So, the care plan would involve strategies aimed at reducing environmental stress, teaching the patient stress management techniques, and promoting adherence to antipsychotic medication.

    Delving into the Pathophysiology of Common Disorders

    In the world of nursing, having a grasp on the pathophysiology of common mental disorders is vital. This understanding helps you better appreciate the underlying biological mechanisms that contribute to disorder symptoms and progression. It also aids in illuminating the rationale behind various treatment approaches.

    The Science Behind: Pathophysiology of Common Disorders

    Pathophysiology can be defined as the study of functional changes in the body that occur due to disease, and it provides the basis for many clinical assessments and interventions.

    Pathophysiology is a convergence of pathology (the study of the causes and effects of diseases) with physiology (the study of how the various parts of the body function). Understanding the pathophysiology of a disease refers to understanding the biological processes that are set in motion when an individual gets sick.

    Let's break down the pathophysiology of some common mental disorders:

    • Depression: The pathophysiology of depression involves alterations in neurotransmitter systems, hypothalamic-pituitary-adrenal (HPA) axis disturbances, neuroprogression, and changes in brain structure. The neurotransmitters implicated most often are serotonin, norepinephrine, and dopamine.
    • Anxiety disorders: The biological aspects of anxiety disorders involve several areas of the brain that regulate fear and anxiety, including the amygdala and hippocampus. Imbalances of certain chemicals such as serotonin, dopamine, and norepinephrine can also play a role.
    • Schizophrenia: The exact pathophysiology is unknown but is believed to involve a combination of genetics, brain chemistry, and environment. Neuroimaging studies show differences in brain structure and the central nervous system in people with schizophrenia.
    • Eating disorders: The pathophysiology involves a complex interaction of genetic, biological, behavioural, psychological, and societal influences. Neurobiological factors include hereditary predisposition, brain abnormalities, and neurotransmitter imbalances.
    • Addictive disorders: These are frequently associated with changes in key neurological pathways, especially those involving reward and motivation. Addictive substances are thought to hijack this reward system, causing the release of neurotransmitters such as dopamine in the brain's pleasure centres.

    The human brain is a complex organ, and much still remains unknown about its workings, particularly in the realm of mental health. It's essential to note that the specific pathophysiology can vary significantly even between individuals with the same disorder. Therefore, whilst these descriptions provide a framework, they are by no means exhaustive nor representative of each individual's experience.

    Common Disorders: Impact on Physical and Mental Health

    Beyond their distinct symptoms, common mental health disorders can markedly affect both physical and mental health. They may also increase the risk of co-occurring disorders and have a significant impact on lifespan.

    The impact of these disorders can manifest in multiple aspects of life:

    • Physical health: Mental disorders frequently co-occur with chronic diseases such as diabetes, cardiovascular disease, and obesity. For instance, individuals with severe mental illness have a risk of premature mortality up to 20 years shorter than the general population, primarily due to physical diseases.
    • Mental health: Those with a mental illness have a higher likelihood of experiencing another mental disorder. For example, those with depression often also suffer from an anxiety disorder. Mental health disorders might also increase the risk of suicide.
    • Quality of life: Mental disorders can drastically reduce an individual's quality of life, affecting relationships, work performance, and everyday activities.
    • Social implications: Mental health disorders can lead to social isolation, discrimination, and stigma.

    Let's consider a patient diagnosed with an anxiety disorder. They are constantly experiencing intense, excessive, and persistent worry bout everyday situations. Over time, chronic worry can lead to significant bodily discomfort - such as headaches, nausea, or palpitations - and disrupt sleep patterns. The persistent fear and avoidance might also lead them to withdraw socially, impacting their personal relationships and ability to function at work or school. Hence, their mental disorder is profoundly impacting their physical health, mental and emotional wellbeing, and overall quality of life.

    As a nursing professional, your role will involve addressing these vital areas, alongside disorder-specific symptoms, to ensure a holistic approach to patient care.
