Learning and behavioural changes

The scars from meningitis are not always visible. Whatever the outcome, meningitis can have a huge impact on many aspects of people’s lives

After-effects of meningitis - learning and behavioural LB

After meningitis

Our ongoing research has identified the true impact of meningitis – on the individual, their family, friends, and even our society – highlighting the need for support for life.

Learning and behavioural problems

  • Learning difficulties and behavioural problems can happen after meningitis, especially in babies and young children
  • Fortunately, many of these problems are short-term and improve with time
  • However, long term problems, such as aggression and personality changes are often associated with acquired brain injury (ABI) - an injury to the brain after birth

Acquired brain injury (ABI)

Both meningitis and septicaemia can cause an ABI. 

  • An acquired brain injury (ABI) can also cause more subtle changes. The brain takes over 20 years to fully develop, so if a child or young adult has meningitis the development of the brain can be affected
  • The changes may not be apparent immediately after the illness. It may take months or even years before any changes are noticed
  • When problems are more subtle, for example irritability, difficulties concentrating, clumsiness, temper tantrums and sleep disorders, it is sometimes difficult to be sure that these problems are caused by meningitis. It is not always easy to get the right help and support


Our research project MOSAIC, published in Lancet Neurology, confirms that meningococcal disease (most common cause of bacterial meningitis) has a lifelong impact, leaving a significant number of survivors with reduced IQ and problems with memory, concentration and planning. The research has also shown that survivors are significantly more likely to need additional educational support or experience mental health disorders and physical disability.
