Neurocognitive and mental health tests have been recommended by an international taskforce to harmonise the assessment of patients with Long COVID.
The tests and questionnaires can be used internationally and will help to advance global understanding about the impact of the condition on the lives of millions of people worldwide.
“Because COVID-19 is a new disease and the research deriving from it is new, we need to develop excellent research methods to address questions, such as: how many people have the problem, how long does it last, how many patients fully recover, do these neurocognitive difficulties precipitate dementia in some people?,” says lead author and research fellow in UNSW’s School of Psychology, Dr Lucette Cysique.
“Now we will be able to assess these problems in the best way possible using these expert recommendations.”
Dr Cysique – an expert in HIV neuropsychology and one of the first neuropsychologists to recognise that COVID-19 may lead to neurocognitive complications – last year set up a group made up of members of the NeuroCOVID International Neuropsychological Society special interest group, which is now a taskforce of more than 120 members.
She says the NeuroCOVID International Neuropsychology taskforce recommendations encompass brief, medium, and comprehensive evaluations.
The brief evaluation includes a short screening conducted at a patients’ bedside or by telehealth, and short questionnaire to assess olfaction, taste, and mental health.
At the more comprehensive level, there are options for cognitive computerised assessments, standard neuropsychological tests and objective testing of taste and smell.
There are also mental health recommendations that cover a wide range of pandemic stress impacts and pre-existing psycho-social vulnerabilities.
Dr Cysique and her colleagues trialled the recommended methods in the landmark ADAPT study led by Associate Professor Gail Matthews from the Kirby Institute, who is also Head of Infectious Diseases at St Vincent’s Hospital.
The ADAPT study is following over 150 individuals who have had COVID-19 for up to two years to understand how people recover following their infection.
“A significant proportion of individuals continue to have a variety of symptoms, or long COVID, several months after acute infection,” Professor Matthews says.
Researchers within the study are exploring whether abnormalities in the immune response to COVID-19 are driving this new syndrome.
“When studying a new phenomenon such as Long COVID it is critical that we use a set of well validated globally generalisable measures such as these developed by the NeuroCOVID International Neuropsychology taskforce,” Professor Matthews says.
Dr Cysique says the recommended methods showed up to 23 per cent of study participants had neurocognitive difficulties six months after infection.
She says accurately knowing who is experiencing difficulties is the first step for intervention with Long COVID.
“We know that some people develop a ‘brain fog’ such as difficulties in concentrating and paying attention and this can persist months after infection,” Dr Cysique says.
“In some patients, such difficulties are associated with a feeling of generalised fatigue which can be severe enough that people cannot work as efficiently as they used to.”
She says she hopes that the recommendations will lead to the creation of a large global research database that will produce robust research results to determine what is the frequency of neurocognitive problems in people with Long COVID.
“This will assist in developing an accurate picture of what is the burden of neurocognitive difficulties post COVID,” Dr Cysique says.
“This, in turn, will assist in patients’ management and inform health policies.”
