Alzheimer’s disease (AD) causes gradual cognitive decline and dementia. Until recently, the definitive diagnosis of AD was based on autopsy assessments of brain amyloid-β plaques and tau neurofibrillary tangles, the defining biological features of AD.

Biomarkers of amyloid-β and tau are vital for measuring AD pathology in living people and for differentiating between different neurodegenerative diseases. With the latest progress in AD research, accurate in-vivo diagnosis of AD is becoming increasingly crucial.

In this video Joseph Therriault, PhD discusses the AD biomarkers and their use in clinical and research settings and explore future research areas for wider clinical practice use.

Brain Circuitry and Emotional Lability

Emotional lability describes episodes of involuntary and uncontrollable crying and/or laughing, outside of socially appropriate circumstances and when it is incongruent with the patient’s emotional state.
