The symptoms of dementia and how the environment has an impact

  • Memory loss – where am I, why am I here, I don’t recognise anyone, anything, anywhere 
  • Communication skills – forgetting words, not able to speak/explain/ask clearly. Not able to understand what is being said 
  • Emotions – a person with dementia may forget people and places but not how a person makes them feel 
  • Visual perception – lack of spatial awareness (2D & difficulty judging distances), tunnel vision/loss of ability to distinguish between colours 
  • Loss of ability to apply logic and reason (sense danger). Unable to sequence events correctly 
  • Experience increased levels of stress and anxiety 
  • Easily confused and disorientated 


  • Age related ailments – sight, hearing, physical fitness, height, chronic conditions such as high/low blood pressure, diabetes, stroke or heart issues 

Challenging behaviour is very rarely a symptom of dementia, but more likely caused by the environment and people
