Being a tertiary referral centre for neurocognitive problems it caters to patients with amnesia, mild cognitive impairment, dementia, aphasia, neuropsychiatry syndromes and related conditions, arising as a primary disease or as a consequence of other diseases (like stroke), surgery, trauma or other causes are seen in this section. The section conducts a weekly Memory and Neurobehavioral (specialty) clinic.

Comprehensive diagnostic, medical management and counseling services are provided for these patients and their families.

Other Activities

Counseling and Care-giver support to patients with dementia is provided in collaboration with the Alzheimer's & Related Disorders Society of India, (ARDSI), Trivandrum Chapter.

The CBNS provides technical support and advice to the Alzheimer's & Related Disorders Society of India (ARDSI) for its Dementia day-care and full-time care facility 'Sneha Sadanam' in Trivandrum.

Active efforts with ARDSI to generate awareness amongst the medical community and educate the masses about dementia.

In CBNS research is ongoing in the following areas.

Clinical Research: In the Indian population, profiling the symptomatology, evolution and longitudinal course of a) dementias including Alzheimer's disease (AD) and Fronto temporal lobar degenerations (FTLD); b) conditions with early cognitive deficits including Mild Cognitive Impariment (MCI) and Vascular Cognitive Impariment (VCI); c) estimating the dementia burden for the families; d) language deficits in primary progressive aphasias and stroke.

Epidemiological Research: A community based program of long-term longitudinal study of Cognition in Older Adults in Trivandrum (COAT) which is looking at changes in cognition associated with healthy aging, estimating incidence and prevalence of and risk factors (including dietary, gait social networking) and early markers, for mild cognitive impairment, Alzheimer's disease, and Vascular cognitive impairment in urban and rural elderly community dwellers.

Neurogenetics Research: The CBNS, in collaboration with the department of Biochemistry runs a Neurogenetics lab. Here population based genetic studies like estimation of prevalence of various ApoE allelic subtypes, and progranulin and tau gene related studes,

Biotechnology Research: Studies on estimation of serum levels of A-beta in patients with Mild Cognitive Impairment (MCI) and Alzheimer's disease (AD), tau and progranulin levels in patients with Frontotemporal Dementia (FTD) are ongoing. Study of the role of macrophages in clearance of amyloid beta from brain in AD.

Neuroscience & Brain Mapping Research: The CBNC in collaboration with the department of Radiology runs a Brain Mapping lab. Here project on developing a Magnetic Resonance Imaging (MRI) template of Indian Brain, volumetric and voxel based morphometric (VBM) cross-sectional and longitudinal studies of various regions of interest in brains of patients with different dementia and neuropsychiatric diseases and functional MRI (fMRI) studies in some of these conditions are ongoing. Neuroscience fundamental research is being pursued in this lab in three areas- memory, language and vision, using behavioural experiments, fMRI and transcranial magnetic stimulation (TMS).

Neuropsychology & Tool Development Research: Translation and transcription of various neuropsychological instruments to suit the local population and standardization and deriving norms on them. There is also an ongoing project of developing a non-dominant hemisphere language assessment battery. The lab also has a University-Industry partnership collaborative project of developing and standardising a computerised neuropsychological battery for Indian population.
