The Mental State Examination (MSE) in psychology is a structured way of observing and describing a patient's current state of mind, under the domains of appearance, attitude, behavior, mood and affect, speech, thought process, thought content, perception, cognition, insight, and judgement. This assessment tool is crucial in the psychiatric evaluation and helps in diagnosing mental health disorders. It is designed to assess various aspects of a person's psychological functioning at a specific point in time.
Key components of the MSE include:
Consciousness: This assesses the level of alertness and awareness of the environment. It includes checking for states like alert, drowsy, stuporous, or comatose.
Attitude: Observing the patient's attitude towards the examiner and the examination process itself—whether cooperative, hostile, ambivalent, or any other attitude that might affect the interaction.
Dressing: Evaluating how the patient is dressed, which can provide insights into their self-care, social awareness, and current mental state.
Grooming: Observing the patient's personal hygiene and grooming habits, which can indicate their ability to perform daily self-care activities.
Eye Contact: Noting the patient's eye contact can give clues about their social interaction, confidence, anxiety level, or cultural background.
PsychoMotor Activity: Assessing the level of physical movement, which can range from agitated or restless to slowed or absent (catatonia). This also includes observing any unusual movements or gestures.
Speech: Evaluating the patient's speech for rate, volume, tone, fluency, and any abnormalities. This can reveal a lot about their thought processes and emotional state.
Mood: The patient's self-reported emotional state over a period of time. This could be described in the patient's own words.
Affect: The observable expression of emotion, which may or may not match the reported mood. This includes the range, appropriateness, and stability of emotional expression.
Thought Form: Observing the organization and flow of thoughts. This includes assessing for coherence, tangentiality, circumstantiality, or loosening of associations.
Thought Content: What the patient is actually thinking about, including preoccupations, delusions, obsessions, and suicidal or homicidal ideation.
Perception: Checking for any distortions or misinterpretations of sensory information, such as hallucinations (auditory, visual, or other senses) or illusions.
Higher Function: Assessing cognitive functions including orientation (to time, place, and person), attention, memory, abstract thinking, and other executive functions.
Insight: The patient's understanding and acknowledgment of their current condition or situation. This involves recognizing their own symptoms or behaviors as problematic.
Judgment: The ability to make reasonable decisions, understand consequences, and use appropriate problem-solving strategies.
This structured approach ensures a thorough assessment of the patient's mental state, aiding in accurate diagnosis and treatment planning. Each component is crucial for painting a complete picture of the patient's psychological health and functioning.
Expanding on the Mental State Examination (MSE) components, including signs and symptoms with a brief description for each, can provide a more detailed and nuanced understanding of a patient's mental health status. Here's an elaboration on the key categories:
I. Consciousness (state of awareness)
Consciousness in psychology and psychiatry refers to the state of awareness of oneself and the environment. It encompasses the ability to experience thoughts, feelings, and sensations and to perceive and interact with one's surroundings. Consciousness is a multifaceted concept that includes several dimensions, such as wakefulness, self-awareness, and the focus of attention. In the context of a Mental State Examination (MSE), the assessment of consciousness is crucial for understanding a patient's mental state and identifying any potential disturbances that might indicate underlying psychiatric or neurological conditions.
ApperceptionApperception is the process by which new experiences are assimilated into existing cognitive structures and perceptions. It involves the conscious awareness and interpretation of one's environment, allowing individuals to integrate new information with their existing knowledge. Apperception is critical for meaningful interactions with the world and for the continuity of personal identity over time.SensoriumSensorium refers to the total sensory apparatus of the body, encompassing the ability to perceive and process sensory information from the environment. It includes the function of all senses (sight, hearing, touch, taste, and smell) and the integration of this sensory data by the brain to form a coherent perception of the environment. The clarity and accuracy of the sensorium are essential for effective interaction with the world.Disturbances of Consciousness
Disturbances in consciousness can range from mild confusion to complete unresponsiveness, significantly affecting an individual's ability to perceive, react to, and interact with their environment.
1. Disorientation
Disorientation is a confusion about time, place, or person. It signifies an impairment in consciousness and is often seen in neurological and psychiatric conditions.
2. Delirium
Delirium is an acute, fluctuating state of confusion characterized by disturbed consciousness, cognitive dysfunction, and impaired attention. It often has a reversible cause, such as infection, intoxication, or metabolic imbalance.
3. Coma
Coma is a state of deep unconsciousness in which an individual cannot be awakened, fails to respond normally to painful stimuli, light, or sound, lacks a normal wake-sleep cycle, and does not initiate voluntary actions. It results from significant injury or illness affecting the brain.
Disturbances of Attention
Attention disturbances affect how an individual focuses, maintains, and shifts attention.
1. Distractibility
Distractibility is an excessive tendency to shift attention in response to irrelevant or trivial stimuli, making sustained focus on tasks difficult.
2. Selective Inattention
Selective inattention, or attentional bias, occurs when an individual consistently fails to attend to certain stimuli or information while focusing excessively on others, often based on the perceived emotional significance of the ignored stimuli.
3. Hypervigilance
Hypervigilance is an enhanced state of sensory sensitivity accompanied by an exaggerated intensity of behaviors whose purpose is to detect threats. It is often seen in anxiety disorders, such as PTSD.
Disturbances in Suggestibility: Hypnosis
Hypnosis is a state of increased suggestibility, where an individual is more likely to accept and act on suggestions from others. It involves focused attention, reduced peripheral awareness, and an enhanced capacity to respond to direction. Hypnosis can be used therapeutically to alter perceptions, sensations, emotions, thoughts, or behavior.
II. Attitude
Cooperative: Willingly participates in the examination.
Hostile: Shows resistance or aggression towards the examiner.
Suspicious: Displays mistrust or paranoia during interaction.
Apathetic: Shows a lack of interest or concern.
III. Dressing and Grooming
Neat: Indicates self-care and possibly a stable mental state.
Disheveled: May suggest neglect or a decline in mental functioning.
Inappropriate: Clothing not suitable for the situation, possibly indicating a disconnection from reality.
IV. Eye Contact
Direct: May indicate confidence and willingness to interact.
Avoidant: Can suggest anxiety, fear, or discomfort.
Fixed: Intense and unblinking eye contact, possibly signaling aggression or psychosis.
V. Psychomotor Behaviour (Conation)
Psychomotor behavior, or conation, refers to the connection between mental processes and physical movement. It encompasses a wide range of actions stemming from the mind that manifest in voluntary and involuntary movements or behaviors. This aspect of psychological functioning is critical for understanding many mental health disorders, as changes in psycho-motor behavior can be significant indicators of various psychiatric conditions.
1. Echopraxia
Echopraxia is the involuntary imitation of another person's actions. It is often seen in certain psychiatric conditions like schizophrenia.
2. Catatonia
Catatonia is a psychomotor syndrome characterized by an inability to move normally and can include a variety of symptoms:
Catalepsy: A condition where the person maintains rigid body positions for long periods.
Catatonic Excitement: Excessive motor activity that is seemingly purposeless and not influenced by external stimuli.
Catatonic Stupor: A state where the person is mute, immobile, and exhibits a lack of responsiveness to the environment.
Catatonic Rigidity: Maintaining a rigid posture against efforts to be moved.
Catatonic Posturing: Voluntary assumption of inappropriate or bizarre postures.
Cerea Flexibilitas (Waxy Flexibility): Limbs remain in the position they are placed by another person.
Negativism: Automatic opposition or resistance to instructions or external stimuli.
3. Cataplexy
A sudden loss of muscle tone triggered by strong emotions, often associated with narcolepsy.
4. Stereotypy
Repetitive, fixed patterns of physical action or speech that are purposeless but can be driven by underlying neurological or psychiatric conditions.
5. Mannerism
Odd, exaggerated movements or behaviors that are stylized and seem to have a purpose but are actually purposeless.
6. Automatism
Automatic behaviors performed without conscious awareness, often complex and seemingly purposeful.
7. Command Automatism
Performing actions automatically in response to verbal commands, often without awareness of the action.
8. Mutism
An inability or refusal to speak, which can be a result of psychological or neurological conditions.
9. Overactivity
This includes various forms of excessive movement or behavior:
Psychomotor Agitation: Restlessness and repetitive, often purposeless movements associated with anxiety or other mental health conditions.
Hyperactivity: Excessive movement, difficulty with impulse control, and attention difficulties, commonly associated with ADHD.
Tic: Sudden, repetitive, nonrhythmic motor movements or vocalizations.
Sleepwalking: Engaging in activities that are usually performed during a state of full consciousness while asleep or in a sleeplike state.
Akathisia: A state of agitation, distress, and restlessness that is an urgent side effect of certain medications.
10. Compulsion
Compulsions are repetitive behaviors driven by an irresistible urge, often performed in response to an obsessive thought:
Dipsomania: An uncontrollable craving for alcohol.
Kleptomania: Compulsion to steal items not needed for personal use or monetary value.
Nymphomania and Satyriasis: Outdated terms, now referred to as hypersexuality, indicating an excessive preoccupation with sexual thoughts, urges, or behaviors.
Trichotillomania: Compulsive hair pulling, leading to hair loss.
Ritual: Repetitive behaviors or rituals performed according to certain rules, often seen in OCD.
11. Mimicry
The act of imitating or copying the actions, speech, or behaviors of others, which can be a form of social learning or a symptom of certain psychiatric conditions.
12. Aggression
Behaviors or attitudes that show readiness to attack or confront, which can be physical or verbal, and is often a symptom of underlying mental health issues.
13. Acting Out
Performing actions that express thoughts or feelings that have not been verbalized, often in a destructive or disruptive manner, usually as a response to emotional conflict.
Understanding and identifying these varied psycho-motor behaviors and disturbances are crucial in diagnosing and treating psychiatric disorders, offering insights into the underlying mental health conditions affecting individuals.
VI. Speech
Disturbances in speech encompass a range of abnormalities in the way ideas, thoughts, and feelings are expressed through language. These disturbances can significantly impact an individual's ability to communicate effectively with others. Here are definitions and examples for the specified speech disturbances:
1.Pressure of Speech
Definition: Pressure of speech is a rapid, continuous flow of verbalization in which the person feels compelled to keep talking. This condition is characterized by fast, incessant talking that is difficult to interrupt. It often occurs in manic episodes of bipolar disorder.
Example: A person with pressure of speech might jump quickly from topic to topic without any prompts from others, speaking rapidly and frenetically, making it hard for listeners to follow or get a word in edgewise.
2. Poverty of Speech (Alogia)
Definition: Poverty of speech refers to a reduction in the amount of speech, where the individual's responses to questions are brief and communication is minimal. This condition is often seen in schizophrenia and other disorders characterized by diminished thought processes.
Example: When asked how they are feeling, a person with poverty of speech might simply reply, "Okay," and provide no further details, even with prompts for more information.
3. Poverty of Content of Speech
Definition: Despite a normal quantity of speech, the actual content of what is said is insufficient and lacks meaningful information. The speech may be long-winded, but it conveys little of substance. This can also be observed in schizophrenia, among other conditions.
Example: A person may speak at length about their day, detailing every meal they had or the weather, but not actually convey any significant information or answer the question posed to them, such as how they are feeling or what they did at work.
4. Dysarthria
Definition: Dysarthria is a motor speech disorder resulting from neurological injury of the motor component of the motor-speech system. It is characterized by poor articulation of phonemes (sounds of speech), which makes the person's speech difficult to understand. It can be caused by a stroke, brain injury, or other neurological conditions affecting the muscles used for speaking.
Example: A person with dysarthria may slur their words, speak very softly or slowly, and have difficulty pronouncing certain letters or words, making their speech hard to understand.
These speech disturbances can significantly impact an individual's social interactions, personal relationships, and overall quality of life, highlighting the importance of recognizing and addressing them in clinical settings.
VII. Mood
Mood refers to a pervasive and sustained emotion that colors the individual's perception of the world. It is subjectively experienced and reported by the patient and can also be observed by others. Here are definitions and examples for the specified mood states, followed by a graphic representation of these moods arranged from neutral at the center, happy moods ascending, and sad or negative moods descending:
1. Dysphoric Mood
Definition: A general feeling of unhappiness or dissatisfaction with life. Example: Feeling consistently sad, dissatisfied, or unhappy, regardless of the situation.
2. Euthymic Mood
Definition: A state of being in which a person experiences a mood that is considered normal or typical, without significant highs or lows. Example: Feeling stable and content, neither particularly sad nor happy.
3. Expansive Mood
Definition: A mood state characterized by unrestrained emotional expression, often with an overestimation of one's significance or importance.
Example: Feeling extremely confident and outgoing, talking to everyone about one's grand plans.
4. Irritable Mood
Definition: A mood characterized by a reduced tolerance for frustration, leading to easy annoyance or anger.
Example: Getting quickly annoyed or angered by minor inconveniences.
5. Labile Mood
Definition: A mood that changes rapidly and unpredictably. Example: Swinging from joyful tears to angry outbursts within minutes without a clear reason.
6. Elevated Mood
Definition: A mood state characterized by a feeling of increased energy and optimism, higher than usual but not necessarily pathological. Example: Feeling unusually upbeat and energetic, more so than the typical baseline.
7. Euphoria
Definition: A feeling of intense happiness and well-being, often beyond what is considered normal.
Example: Feeling an intense, overwhelming sense of joy and happiness, without any specific cause.
8. Ecstasy
Definition: An extreme state of joy and delight, often leaving one out of touch with reality.
Example: Feeling overwhelming happiness and joy, to the point of being absorbed in a blissful state, disconnected from everyday concerns.
9. Depression
Definition: A mood state characterized by feelings of sadness, emptiness, and despair that are persistent and interfere with daily life.
Example: Feeling hopeless and lacking energy or interest in life, persisting for weeks or longer.
10. Anhedonia
Definition: The inability to feel pleasure in normally pleasurable activities. Example: Finding no enjoyment in activities that used to bring joy, such as spending time with loved ones or pursuing hobbies.
11. Grief or Mourning
Definition: A deep sorrow, especially caused by someone's death. Example: Experiencing intense sadness and longing after the loss of a loved one.
12. Alexithymia
Definition: A personality construct characterized by the subclinical inability to identify and describe emotions in the self.
Example: Struggling to recognize what you're feeling or to describe emotions to others.
13. Anxious Mood
Definition: A state of excessive worry, nervousness, or unease about something with an uncertain outcome.
Example: Constantly feeling worried about future events, even when there is no apparent reason to worry.
14. Elated

Example: Feeling extremely happy and optimistic, as if nothing could bring you down.
15. Exalted
Definition: A state of extreme happiness or elevation, often with a sense of pride or loftiness.
Example: Feeling a sense of intense joy and pride, often related to a personal achievement or spiritual upliftment.
VI. Affect
Affect refers to the external display of emotions or feelings, which can be observed by others. It includes facial expressions, gestures, tone of voice, and other nonverbal cues that indicate how a person is feeling. Affect can indeed vary over time and in response to different emotional states or situations. Here are definitions and examples of various types of affect:
1. Appropriate Affect
Definition: The individual's emotional expression is consistent with the content of what they are saying or with the situation they are in. Example: Smiling and showing pleasure when talking about a happy event, or appearing sad when discussing a loss.
2. Inappropriate Affect
Definition: The emotional expression does not match the content of the speech or the situation.
Example: Laughing while describing a tragic event, or showing no distress when talking about something that is generally considered upsetting.
3. Blunted Affect
Definition: A significant reduction in the intensity of emotional expression. Example: Showing very mild sadness when discussing a situation that would typically cause profound grief.
4. Restricted Affect
Definition: A mild reduction in the range and intensity of emotional expression, less severe than blunted affect.
Example: Displaying a limited smile when hearing good news, showing less emotion than expected.
5. Flat Affect
Definition: A lack of any observable emotional expression, the face is immobile, and the voice monotonous.
Example: Showing no emotional response to events or situations that would typically elicit strong emotions, such as joy at a wedding or sadness at a funeral.
6. Labile Affect
Definition: Rapid and abrupt changes in emotional expression. Example: Quickly shifting from laughing to crying without an apparent reason, reflecting a highly unstable emotional state.
Note: - La Bella IndifferenceLa Bella Indifference refers to an unusual lack of concern or indifference toward one's significant physical or psychological symptoms. It is not directly a type of affect but rather a psychological phenomenon often observed in some psychiatric or neurological conditions, such as conversion disorder (functional neurological symptom disorder).
Example: A person who has suddenly lost the ability to move their arm but appears unconcerned or dismissive about this significant impairment might be described as showing la Bella indifference.
La Bella indifference is not categorized under affect because it pertains more to the person's attitude or reaction towards their condition rather than the external expression of emotions. However, the outward manifestation of this indifference can influence how one's affect is perceived, especially in clinical assessments where emotional responses to one's health status are considered.
VIII. Thought
Specific disturbances in the form of thought and content of thought are important aspects to consider during a Mental State Examination (MSE). These disturbances can provide valuable insights into various psychiatric conditions.
Specific Disturbances in Form of Thought
Neologism: Making up new words that only have meaning to the individual. Example: A patient uses the word "floritab" without explaining its meaning.
Word Salad: Random words or phrases linked together in an incoherent way.Example: "Apple desk, run happiness tree, blue."
Circumstantiality: Providing unnecessary detail but eventually reaching the point.Example: Taking a long time to answer a simple question due to excessive detail.
Tangentially: Going off-topic without answering the original question.Example: Asked about their day, a patient starts discussing unrelated topics like the weather.
Incoherence: Speech that is difficult to understand due to illogical connections.Example: "The cow mooned loudly at the door to paint a new cheeseburger."
Perseveration: Repetitive and persistent response to a stimulus or question.Example: Continuously repeating the same phrase or answer, regardless of the question.
Verbigeration: Meaningless repetition of specific words or phrases.Example: Repeating "blue, blue, blue" without any context.
Echolalia: Parroting or mimicking another person's speech.Example: Repeating questions instead of answering them.
Derailment: Speech where ideas slip off the track onto another which is clearly but indirectly related.Example: Mid-sentence, the subject changes abruptly to an only vaguely related topic.
Flight of Ideas: Rapid shifting from one idea to another, seen in manic episodes.Example: Jumping quickly between topics that are loosely connected.
Specific Disturbances in Content of Thought
Poverty of Content: Speech that is long but conveys little information.Example: Talking at length with little substantive content.
