Taking a history for a suspected case of dementia involves a comprehensive approach that aims to gather detailed information about the onset, progression, and impact of symptoms on the patient’s daily life. The process includes gathering information from both the patient and a reliable informant, such as a family member or caregiver, who can provide insight into the changes in the patient’s cognitive and functional abilities. Here’s a structured approach:
- Presenting Symptoms:
- Begin by asking about the main concerns or changes noticed in memory, thinking, or behavior.
- Clarify when these symptoms began and how they have progressed over time.
- Detailed History of Cognitive Symptoms:
- Memory: Assess both short-term and long-term memory. Ask about forgetting recent conversations, appointments, misplacing objects, or repeating questions.
- Language: Look for difficulties in naming objects, following conversations, or expressing thoughts.
- Executive Function: Investigate challenges in planning, organizing, problem-solving, or decision-making.
- Visuospatial Abilities: Ask about difficulties in recognizing faces or objects, getting lost in familiar places, or handling tools.
- Attention and Concentration: Assess if there is difficulty in focusing on tasks or being easily distracted.
- Behavioral and Psychological Symptoms:
- Personality Changes: Note any changes in behavior, such as increased apathy, social withdrawal, agitation, aggression, or disinhibition.
- Mood Changes: Look for symptoms of depression, anxiety, or unusual fluctuations in mood.
- Impact on ADLs (Activities of Daily Living):
- Assess how cognitive changes have affected the ability to perform everyday tasks, such as managing finances, driving, cooking, shopping, and personal care.
- Medical History:
- Gather information about past and current medical conditions, especially those that can impact cognitive functioning like hypertension, diabetes, heart disease, stroke, head injuries, and psychiatric illnesses.
- Medication Review:
- Review all medications, including over-the-counter drugs and supplements, as some medications can affect cognitive functions.
- Family History:
- Inquire about a family history of dementia, neurological diseases, or psychiatric conditions.
- Social History:
- Understand the patient’s education level, occupation, alcohol and tobacco use, and social support system.
- Mood Assessment:
- Screen for depression and anxiety, which can co-occur with or mimic dementia.
- Safety Assessment:
- Evaluate any risks related to the patient’s cognitive impairment, like wandering, forgetting to turn off appliances, or driving difficulties.
- Cognitive Assessment:

- Functional Assessment:
- Use tools like the Activities of Daily Living (ADL) and Instrumental Activities of Daily Living (IADL) scales to assess the patient’s ability to manage daily activities.
Remember, taking a dementia history is sensitive and requires a respectful and empathetic approach. The goal is to gather accurate information to guide diagnosis and care planning while maintaining the dignity and comfort of the patient.
