glossary of terms 

Agnosia: is the loss of the ability to recognise familiar people or objects by sight, touch, taste, smell, or sound.

 

Anomia: is an inability to remember or recognise the names of objects and may become increasingly noticeable as the condition progresses.

 

Apraxia: is the inability to complete a practised and familiar motor task such as buttoning up a shirt. Even though the desire to carry out the task is present and all of the parts of the brain needed to do so are functioning, the communicative link between the ‘thinking’ and ‘doing’ parts of the brain is broken.

 

Creutzfeldt Jacob Disease (CJD): is a disease caused by the presence of rogue prions which alter proteins in the body in such a way that they rapidly harm the body’s central nervous system and brain. CJD is an extremely rare condition affecting an estimated one in every million people.

 

Cerebellum: This is the area of the brain responsible for controlling our balance and coordination.

 

Cognition: is a collective term for the thought processes which enable our perceptions, understanding and reasoning of ourselves and our environment.

 

Dysarthria: is an inability to speak clearly as a result of the loss of coordination of the muscles associated with speech.

 

Dysphagia: is the medical term for the symptom of difficulty in swallowing

 

Dysphasia: is a partial or complete impairment of the ability to communicate results from a brain injury that can be caused by dementia

 

Frontal Lobe: This area of the brain immediately behind the forehead is associated with our personality, emotions, reasoning, planning, problem-solving and aspects of speech.

 

Hippocampus: This is the region of the brain responsible for emotion and short-term memory.

 

Korsakoff’s Syndrome: This form of dementia is often associated with heavy drinking and alcoholism and is a degenerative brain disease. Symptoms include the loss of short-term memory and the inability to learn and retain new skills.

 

Mild Cognitive Impairment (MCI): is defined as a cognitive problem which is sufficiently severe as to be noticed by other people but insufficiently serious as to have a negative impact upon everyday life.

 

Occipital Lobe: Situated at the lower rear of the brain, the occipital lobe is responsible for sight and our ability to recognise objects.

 

Neurodegenerative Disease: A condition such as Alzheimer’s or Parkinson’s disease which is characterised by the progressive degeneration of brain tissue resulting in impaired brain activity and cognitive function. Neurodegenerative diseases most often affect older people.

 

Parietal Lobes: Located behind the frontal lobes at the upper rear of the brain, the parietal lobes process sensory nerve responses such as touch, taste, pressure, temperature and pain. They are also connected to some language functions.

 

Parkinson’s Disease: A slow, progressive degenerative disease of the brain, Parkinson’s disease results from the death of cells called neurons which are vital to the correct functioning of the central nervous system. In addition to dementia, symptoms of Parkinson’s disease include muscle tremor, impaired speech and restricted movement.

 

Person-centric Care: is a holistic and individually-tailored approach to dementia care which is built around the needs of the person with dementia and takes into account their past and present lifestyle, experiences, character and personal preferences.

 

Temporal Lobes: The brain’s temporal lobes can be found just above each ear and are responsible for processing auditory information i.e. whatever we hear. They are also connected with memory, the interpretation of meaning, language, emotion and learning.

​

Vascular Dementia: is often the result of a stroke or a series of ‘mini-strokes’ which restrict the supply of blood to the brain and cause brain tissue to die. Contributory factors to the onset of vascular dementia may include high blood pressure, obesity, diabetes and heart disease. The impairment of cognitive function progresses step-by-step, with concentration and mood noticeably severely affected. The likelihood of vascular dementia increases with strokes which afflict the left hemisphere of the brain or the hippocampus.
