What is Dementia?

“Dementia” describes a set of characteristic symptoms that may include memory loss and trouble with thinking, problem-solving, and / or language.  The International Classification of Diseases, Tenth Edition refers to dementia as “Neurocognitive Disorder.”  There are actually several types of dementia based on both how the symptoms were brought about and what particular symptoms are displayed.

Each person will experience dementia somewhat differently.  Generally, the symptoms often are mild in intensity and often subtle at the outset of the disease progression and can intensify over time.  A person with dementia will frequently have some combination of the following cognitive and emotional symptoms:

  •   Memory Loss
  •   Trouble Concentrating or Organizing Activities
  •   Language Impairment – such as trouble following a conversation or finding the right words to say
  •   Impaired Visuospatial Skills – for instance, trouble judging distances, navigating stairs, or seeing objects in three dimensions
  •   Impaired Orientation – for example, losing track of the day, date, or where they are
  •   Changes in Mood – such as becoming frustrated or irritable, growing anxious or withdrawn, or becoming unusually sad
  •   Changes in Perception – for instance, experiencing delusions or hallucinations

As was mentioned previously, dementia is often progressive.  In later stages, there can be physical symptoms and gradual deterioration in the body and functioning including muscle weakness, weight loss, reduced appetite, impaired sleep patterns, and swallowing difficulty.

There are several sub-types of dementia including Alzheimer’s disease, Vascular dementia, Lewy Body dementia, and Frontotemporal dementia.  The causes of some dementia is readily apparent and can be easily detected with available medical examination and imaging.  For example, Vascular dementia is typically caused by a stroke and symptoms are characterized by where in the brain the stroke occurred.  However, other types of dementia, like Alzheimer’s disease, are not as easy to pinpoint cause.  Dementia is often diagnosed through a combination of medical examination and confirmatory evaluation by a neuropsychologist.
