    • Post-stroke depression often peaks between 3-6 months after the stroke.
    • Cognitive and emotional disorders associated with stroke may fluctuate in relation to the progression of the neurological disease.

    Psychogenic Nonepileptic Seizures (PNES)

    • Seizure-like episodes that are not caused by abnormal brain activity, but rather by psychological factors like stress or emotional distress.
    • Often misdiagnosed as epileptic seizures.
    • Account for 20-30% of patients referred for intractable seizures.
    • Prevalence in the general population is estimated at 2-33 cases per 100,000 people.
    • Classified as a Functional Neurological Disorder in the ICD-11, requiring extensive evaluation to rule out organic causes before diagnosis.

    Psychiatric Manifestations of Parkinson's Disease (PD)

    • Depression is the most common psychiatric symptom associated with PD.
    • Anxiety is another frequent symptom.
    • Psychosis is rare in untreated individuals, but can be triggered by anti-parkinsonian medications, leading to hallucinations and delusions.
    • Dementia in PD typically manifests as sub-cortical dementia with impaired executive function, personality changes, and memory impairment.
    • Dopamine dysregulation syndrome, a complication of dopamine replacement therapy, can cause impulse control disorders.
    • Deep brain stimulation implants for PD have been linked to cases of acute severe psychosis that resolves upon reducing the stimulation.

    Psychiatric Manifestations of Head Injuries

    • Head injuries can be classified as open, closed, acceleration/deceleration, focal/diffuse, each impacting the severity and type of impairment.
    • Common consequences include amnesia (both anterograde and retrograde).
    • Cognitive impairments can lead to personality and behavioral changes.
    • Mood disorders are prevalent, with up to 50% of individuals experiencing depression after a traumatic brain injury (TBI). Mania, though less common than depression, can occur and is typically shorter in duration.
    • Increased risk of suicide is associated with TBI.
    • Psychosis can occur following TBI, with a higher risk for schizophrenia. Post-traumatic psychosis generally has a better prognosis than primary psychotic disorders and fewer negative symptoms. Brain damage associated with post-traumatic psychosis typically involves the frontal and temporal lobes, unlike schizophrenia, which is often associated with enlarged ventricles on brain scans.
    • Increased anxiety disorders are a common consequence of TBI.

    Substance Abuse Disorders and Head Injuries

    • A bidirectional relationship exists between substance abuse disorders and head injuries.
    • Alcohol or other drugs are directly involved in over 33% of incidents causing brain injury.

    • A thorough work-up is essential to exclude any organic or neurological causes before diagnosing PNES.

    Traumatic Brain Injury (TBI) - Psychiatric Manifestations

    • Depression is a common psychiatric manifestation of TBI, affecting up to 50% of individuals.
    • TBI can lead to post-traumatic psychosis, which generally has a better prognosis than primary psychotic disorders.
    • Alcohol and drugs are involved in over 33% of incidents causing TBI.

    Substance Abuse and TBI

    • Substance misuse is increased following TBI.
    • TBI does not decrease the risk of developing substance abuse disorders.

    Neuropsychiatric Conditions

    • Huntington's Disease (HD): A genetic, autosomal dominant neurodegenerative disorder characterized by a trinucleotide repeat expansion.
    • Symptoms: Motor abnormalities, cognitive disturbance, and psychiatric symptoms.
    • Psychiatric Symptoms: Depression is the most common psychiatric manifestation of HD, with two peaks: initial stages and during stage 2 when independence decreases. Both periods are associated with increased suicide risk.
    • Other Psychiatric Conditions: Psychosis, mania, bipolar disorder, anxiety, and obsessive-compulsive disorder (OCD).
    • Multiple Sclerosis (MS): An autoimmune disease affecting the white matter of the central nervous system.
    • Psychiatric Symptoms: Cognitive deterioration (attention, concentration, memory, impaired decision making), mood lability, and depression.
    • Depression in MS: The most prevalent psychiatric symptom, affecting 50% of individuals. Increased suicidal ideation and suicide attempts are also observed.
    • Differential Diagnosis of Depression: It is essential to differentiate between primary mood disorders and drug-induced low mood. Medications like steroids, interferon, baclofen, dantrolene, and tizanidine can cause depression as a side effect.

    Multidisciplinary Approaches in Neuropsychiatric Illness Management

    • Delirium: Frequent in hospital settings, often referred to psychiatry, but has an organic etiology.
    • Behavioral Symptoms: Aggression, disinhibition, and impulsivity are common among neurological patients, requiring careful assessment to distinguish from anxiety, agitation, and mania.
    • Comprehensive Evaluation: Detailed history, physical examination, and reviewing relevant investigations are crucial to differentiate comorbid or additional psychiatric conditions (e.g., new onset anxiety, depression, or psychosis) from deterioration related to medical factors (e.g., medication changes).
    • Collaboration: Effective management requires collaboration between liaison psychiatry and medical colleagues.
    • Clear Referrals: Referrals should be comprehensive and include sufficient information for effective assessment.
    • Proactive Problem-Solving: A proactive approach to problem-solving is essential.
    • Medical Context: Understanding the medical illness and its impact on psychiatric presentations is crucial.
    • Psychiatric Context: Understanding psychiatric illness and its influence on medical presentations is equally important.
    • Comorbidity: Awareness of common comorbid conditions is key.
    • Multidisciplinary Team (MDT): Active consideration of roles for all MDT members is essential - psychology, occupational therapy, social work, nursing, and medical specialties.

    Huntington’s Disease

    • Most common psychiatric symptom: Depression
    • Depression peaks during the middle stages of the disease
    • Independence diminishes during this stage

    Multiple Sclerosis

    • Common psychiatric symptoms: Cognitive deterioration, mood lability, and depression

    Neuropsychiatric Illness in Hospital Settings

    • Multidisciplinary approach is crucial for managing neuropsychiatric illness in a hospital setting.

    • A comprehensive work-up to rule out organic causes is key in diagnosing PNES.

    Seizures

    • Anxiety, depression, and paranoia are common psychiatric manifestations during the post-ictal period of seizures.

    Epilepsy and Psychiatric Management

    • It is important to consider psychiatric symptoms in epilepsy as part of a holistic treatment plan.
    • Neurologists should work collaboratively with other healthcare professionals in a multidisciplinary team (MDT) to address both medical and psychiatric symptoms.

    Neurological and Psychiatric Conditions

    • It's crucial to be aware of how neurological conditions affect psychiatric symptoms and vice versa when treating patients with both neurological and psychiatric conditions.

    Psychiatric Consequences of Head Injury

    • Depression after TBI is common and can increase the risk of suicide.
