It is common that people who have sustained a spinal cord injury may also notice that there are changes to their thinking skills such as memory or concentration. Collectively, our thinking skills are referred to as cognition.
There are often several reasons as to why people may experience cognitive difficulties following a spinal injury. This can include:
- It may be that during an accident which damaged the spinal cord, the brain was also damaged. This is quite common if someone has fallen from a height, struck their head, or been in an accident involving speed. Brain injuries can range from mild concussions which resolve quickly and entirely to a more severe brain injuries which may require assessment and additional rehabilitation.
If there is a concern that there is also a brain injury, the units neuropsychologist will be involved more in your care. There is lots of useful information about brain injury available from Headway.

For some, the cause of their cognitive difficulties can be much less specific and may be attributable to a combination of factors such as:
- Mental health
- Poor sleep
- Pain
- Medication
- Prior significant drug and alcohol use
Some people may have been experiencing mild changes to their cognition prior to their spinal injury. This may have been related to normal ageing or in some cases, may have been due to conditions which become worse over the course of time such as dementia.
The stresses of sustaining a spinal injury may mean those with underlying weaknesses in their cognition are more prone to worsening difficulties during their hospital stay, particularly if they should become unwell of have an infection.
Delirium
Delirium refers to the rapid onset of altered mental functions. During a period of delirium, a person typically presents as confused, agitated, and finds it difficult to remember from one moment to the next. They may act in a very different way to normal and may do or say things which are out of character. At times they may see or hear things we cannon which can be distressing for both the individual and for relatives watching on.
The onset of delirium can be rapid and it can last from a few days to several weeks. Following spinal injury, delirium is often secondary to infection, but there are several risk factors which include:
- Older age
- Existing cognitive weakness
- Immobility
- Infection
- Sensory impairment
- Low levels of stimulation
- Being sedated / ventilated / on a high dependency ward
Most people recover well from delirium. However, for some, it may be that they do not quite return to their prior level of function.
There is a useful handout below which explains more about delirium and how it is managed in hospital settings.
