Mental Status Examination:

  1. MOCA 28/30 difficulty with attention and delayed recall;
  2. ASRS-5 21/24

Differential Diagnoses:

  1. Vascular dementia (VaD) – Primary diagnosis
  2. Attention deficit hyperactivity disorder (ADHD)
  • Alzheimer’s disease (AD)
  1. Frontotemporal dementia (FTD)

Vascular Dementia (VaD)

Vascular Dementia is the primary diagnosis for this client. This condition is characterized by trouble with memory, slowed thinking, difficulty with organization and solving complex problems, or being easily distracted (Zheng et al., 2019). Additionally, individuals with this condition experience mood or behavior changes, including irritability, depression, or loss of interest. The client qualifies for this diagnosis since she reported difficulty with attention and delayed memory. The client also reported being disorganized and forgetting where he kept his item. He is slow in completing assigned tasks at his workplace, delaying meeting the deadline. Stroke and hypertension are significant risk factors for vascular dementia (VaD). Having a history of hypertension the client is at a high risk of VaD. Therefore, Vascular Dementia qualifies as the primary diagnosis for this client.

Attention Deficit Hyperactivity Disorder (ADHD)


The client also qualifies for an ADHD diagnosis. ADHD is a neurodevelopmental disorder characterized by various symptoms, including excessive amounts of inattention, being unable to sit still, hyperactivity, impulsivity, irritability, absent-mindedness, difficulty focusing, forgetfulness, short attention span, or problem paying attention (Mukherjee et al., 2022). The client might have this disorder since he reported difficulty with attention, hyperactivity, irritability, absent-mindedness, difficulty focusing, forgetfulness, and short attention span. However, ADHD was ruled out due to the absence of significant symptoms, including impulsivity and irritability.

Alzheimer’s Disease (AD)

AD is another potential diagnosis for this client. It is characterized by confusion and increased memory loss, inability to learn new things, the problem with reading and difficulty with language, inability to organize thoughts or think logically, shortened attention span, and challenges in coping with new situations (Folch et al., 2018). The client qualifies for this diagnosis since he reported difficulty with attention and delayed memory. However, this condition is ruled out due to the absence of significant symptoms, including confusion, the problem with reading and difficulty with language, inability to organize thoughts or think logically, and challenges in coping with new situations.

Frontotemporal Dementia (FTD)

FTD is the last differential diagnosis for this client. This condition is characterized by language problems, getting distracted easily, and organization and planning difficulties (Young et al., 2018). The client qualifies for this diagnosis since he reported getting distracted easily and having difficulty organizing her personal properties. However, this condition was ruled out due to the absence of language problems.


I agree with the preceptor’s assessment and diagnostic impression of this client. The presented clinical manifestations, including being easily disrupted and short attention span characterize Vascular dementia (VaD). Additionally, the client’s Montreal Cognitive Assessment (MoCA) score was 28/30, indicating difficulty with attention and delayed recall. From this case, I learned that differential diagnosis should be conducted to rule out other neurocognitive disorders with overlapping disorders. If I was treating this client again, I would gather more health-related information to guide me in making an appropriate diagnosis for this client. Furthermore, legal/ethical considerations should be considered in treating this patient. By adhering to the ethical principles of beneficence, mental healthcare providers will use their knowledge and skills to benefit the client, through quality healthcare services. Lastly, the treatment plan should target health promotion and disease prevention. The client has a history of hypertension, increasing the risk of heart disease and stroke (Fuchs & Whelton, 2020). Thus, the client should focus on lifestyle modification to reduce the risk of other health conditions related to hypertension.
