Dementia is a progressive condition that impacts memory, cognitive abilities and daily functioning. While memory lapses or confusion may be part of ageing, persistent symptoms could signal an underlying issue. An accurate diagnosis is vital for accessing the right care and support. One critical step in diagnosing dementia is the mental status exam, a tool used to assess cognitive functions.
What is a mental status exam?
A mental status exam is a structured assessment used by healthcare professionals to evaluate cognitive functioning and emotional well-being. This exam consists of a series of questions, tasks and observations aimed at assessing various aspects of an individual’s mental and cognitive abilities. It serves as a vital tool in diagnosing conditions like dementia, depression, delirium or other neurological and psychiatric disorders.
During the exam, healthcare professionals evaluate several domains, including memory, problem-solving skills, attention, language abilities, visual-spatial skills and orientation to time and place. The mental status exam also includes an evaluation of mood, thought processes and behaviour, which can provide critical insights into the person’s overall mental health.
The exam is a key component of a broader diagnostic process, often used in conjunction with medical history, physical examinations, neuroimaging and laboratory tests. Its primary goal is to help healthcare providers identify cognitive impairments and determine whether these changes are consistent with dementia or other medical conditions. The results from a mental status exam can also establish a baseline for monitoring cognitive changes over time and guide treatment or care planning.
What does a mental status exam include?
The exam evaluates several cognitive domains through structured questions and tasks.
Key areas include:
1. Memory
Patients may be asked to recall a list of words, repeat phrases or remember recent events. This helps assess both short-term and long-term memory.
- Example task: Recalling a list of three words after a few minutes.
2. Orientation
This measures awareness of time, place and person.
- Example task: Asking the patient to identify the current date, location or their own name.
3. Attention and concentration
The ability to focus and process information is tested using exercises that require sustained attention.
- Example task: Counting backwards from 100 by sevens or spelling a word backwards.
4. Language Skills
Language comprehension and expression are evaluated, including naming objects, understanding instructions and constructing sentences.
- Example task: Naming everyday objects, like a pen or watch.
5. Problem-solving and executive function
This assesses reasoning, planning and decision-making abilities.
- Example task: Explaining similarities between two objects (e.g., how an apple and a banana are alike).
6. Visual-spatial skills
The exam may include tasks that measure the ability to interpret visual information and spatial relationships.
- Example task: Drawing a clock face and placing the hands at a specific time.
What other tests support the diagnosis?
While the mental status exam is a cornerstone of dementia diagnosis, it is typically part of a broader assessment that includes:
Medical history
A thorough review of medical and family history helps identify potential risk factors or underlying conditions contributing to cognitive changes.
Physical examination
Doctors may conduct a physical exam to rule out conditions such as infections, vitamin deficiencies or hormonal imbalances that can mimic dementia symptoms.
Neuroimaging
Scans like an MRI or CT may be used to detect brain changes, such as atrophy or structural abnormalities, that align with dementia.
Laboratory tests
Blood tests can help identify treatable conditions like thyroid disorders or nutritional deficiencies that may cause cognitive issues.
What to do if you notice symptoms
If you or a loved one are experiencing memory lapses, confusion or difficulty completing everyday tasks, it’s important to seek medical advice.
Early diagnosis allows for:
- Access to appropriate treatments and therapies.
- Better planning for care and support.
- Opportunities to participate in clinical trials or research.
