The Cognitive Disorders Service

The Cognitive Disorders Service runs in parallel with the Dementia Research Centre (DRC), part of the Department of Neurodegenerative Disease at the UCL Institute of Neurology (ION). The clinical and research components form a national centre of excellence for diagnosis and treatment of patients with cognitive problems, and the group is recognised internationally for ground-breaking research in dementia.

All forms of cognitive disorder are seen; however, we have particular expertise in young onset dementia, familial dementias and unusual degenerative diseases. Progressive disorders such as Alzheimer’s disease (AD), vascular dementia or frontotemporal dementia are commonly seen, but other less common disorders also assessed including limbic encephalitis, hereditary leucodystrophies and acquired cognitive problems such as amnesia, aphasia, visuospatial problems, apraxia, facial recognition and executive dysfunction due to varying aetiologies.

What the clinic visit involves

Patients are assessed in a consultant-led multidisciplinary clinic, including neurology, psychiatry, psychology, imaging, specialist nurse, neurophysiology and allied disciplines. 

Where appropriate, patients are investigated on the same day with MRI, psychology and EEG


This is a scan of your brain which takes place within a special (noisy) machine and the process should take under an hour.  You will be asked some questions to make sure there is no reason why you cannot have a scan (e.g. a pacemaker)


These are tests of memory and thinking and may take around one and a half hours – you will be tested on your own but there is a waiting area in psychology department 


This is a record of the brain’s electrical activity, and involves special electrodes being attached, painlessly to the scalp.  It may take an hour 

If necessary patients can be admitted for further investigations to the Day Case Unit at the NHNN and we have a dedicated lumbar puncture clinic for rapid access to spinal fluid assessment. This can be an important part of the diagnostic process. Other modalities of imaging are also available.

In addition to clinical care, all patients are offered the opportunity to participate in clinical trials and other studies at the DRC.
