Dementia is a progressive neurological condition that affects memory, thinking, problem-solving, language and behaviour, gradually interfering with a person’s ability to carry out daily activities. It is caused by damage to brain cells, which disrupts communication between different areas of the brain. There are several types of dementia, including Alzheimer’s disease, vascular dementia and frontotemporal dementia, each with unique symptoms and progression rates.

As of 2025, over 60 million people worldwide are living with dementia, with approximately 1 million individuals affected in the UK alone – a number that is expected to rise. With no cure currently available, early diagnosis and intervention are key to managing symptoms and improving quality of life. Given that employees spend a significant portion of their lives at work, it’s essential for employers to recognise the early signs of dementia, provide appropriate workplace support, and ensure affected employees receive the help and adjustments they need.

Why Early Recognition is Crucial

Dementia symptoms vary from person to person, and in the early stages, they may be subtle or mistaken for stress, aging, or other health conditions. However, spotting these changes early can allow employees to seek medical advice and access support services sooner. Workplace observations can be particularly valuable, as employees often perform tasks at work that they may not in other environments, making changes more noticeable.

Common Signs of Dementia in the Workplace

  1. Decline in Work Performance and Productivity

A noticeable change in an employee’s work performance may be one of the first indicators of cognitive decline. Look out for:

  • Missed deadlines or difficulty keeping up with workload
  • Declining quality of work despite previous competency
  • Challenges with problem-solving, decision-making or adapting to changes
  • Struggles with complex tasks or following instructions

While occasional forgetfulness or stress-related lapses are normal, a consistent pattern of performance decline should prompt further support and investigation.

  1. Memory Difficulties and Forgetfulness

Memory loss is one of the most widely recognised symptoms of dementia. Employees in the early stages may:

  • Frequently forget important details, such as meetings or project deadlines
  • Repeat the same questions or conversations within a short time
  • Misplace items regularly, such as documents, tools or personal belongings
  • Rely on excessive note-taking for tasks they previously handled with ease

If an employee increasingly depends on colleagues to remind them of key information, this may be a sign that intervention is needed.

  1. Language and Communication Struggles

Dementia can affect a person’s ability to express themselves or follow conversations. Signs to watch for include:

  • Struggling to find the right words or using incorrect words in conversations
  • Pausing frequently or hesitating more than usual when speaking
  • Difficulty understanding instructions or following discussions
  • Losing track of conversations or repeating the same statements

These communication barriers can affect confidence, cause frustration and impact workplace interactions.

  1. Behavioural and Emotional Changes

Emotional and behavioural shifts can be an early indicator of dementia, as the condition affects mood regulation. Employers and colleagues may notice:

  • Uncharacteristic mood swings, irritability, or signs of anxiety
  • Withdrawal from colleagues, social interactions, or workplace activities
  • Difficulty managing stress or frustration over minor issues
  • Changes in personality, such as becoming more passive, aggressive, or impulsive

While stress or personal issues can contribute to emotional changes, persistent and noticeable shifts in behaviour should not be ignored.
