This talk will examine how approaches such as ‘big data’ and new ways of delivering clinical trials can improve current services for older people with mental illness (jam today) and identify and deliver new treatments in the future (jam tomorrow).

How inclusive and diverse is non-invasive brain stimulation in the treatment of psychiatric disorders?Indira Tendolkar, Donders Institute for Brain, Cognition and Behavior, Department of Psychiatry. Mental illness is associated with a huge socioeconomic burden worldwide, with annual costs only in the Netherlands of €22 billion. Over two decades of cognitive and affective neuroscience research with modern tools of neuroimaging and neurophysiology in humans have given us a wealth of information about neural circuits underlying the main symptom domains of psychiatric disorders and their remediation. Neuromodulation entails the alteration of these neural circuits through invasive (e.g., DBS) or non-invasive (e.g., TMS) techniques with the aim of improving symptoms and/or functions and enhancing neuroplasticity. In my talk, I will focus on neuromodulation studies using repetitive transcranial magnetic stimulation (rTMS) as a relatively safe, noninvasive method, which can be performed simultaneously with neurocognitive interventions. Using the examples of two chronifying mental illnesses, namely obsessive compulsive disorders and major depressive disorder (MDD), I will review the concept of "state dependent" effects of rTMS and highlight how simultaneous or sequential cognitive interventions could help optimize rTMS therapy by providing further control of ongoing neural activity in targeted neural networks. Hardly any attention has been paid to diversity aspects in the studies. By including studies from low- and middle income countries, I will discuss the potential of non-invasive brain stimulation from a transcultural perspective.

ONS figures suggest that at least 10% of individuals suffering COVID -19 Infection continue to experience several weeks after testing positive, and other studies report the proportions as even higher (e.g. Logue et al., 2021). One of the most prevalent reported symptoms among these “Long Covid” sufferers is cognitive dysfunction (Davis et al., 2020). However, to date the cognitive sequelae of COVID -19 are little understood. There are a number of reasons why COVID -19 infection might be associated with cognitive impairment and mental illness (e.g. Bougakov et al., 2020). In particular, increasing evidence indicates inflammation (e.g. Huang et al., 2020) and dysfunctional clotting (e.g. Taquet et al., 2021) as issues of major concern, both of which have been previously linked to a range of cognitive deficits (e.g. Vintimilla et al., 2019; Cumming et al., 2013). Indeed, evidence is beginning to emerge that cognitive issues may be widespread in the post-infection period, particularly among hospitalised and ventilated patients (e.g. Hampshire et al., 2020; Alemanno et al,. 2020). Here I shall present “Hot off the [SPSS]Press” results from a study on memory and cognition following COVID infection in a non-hospitalized cohort.

Social interactions are central to the human experience, yet it is also one of the faculty of the brain that is the most impaired by mental illness. Similarly, social interactions are essential for animals to survive, reproduce, and raise their young. Over the years, my lab has attempted to decipher the unique characteristics of social recognition: what are the unique cues that trigger distinct social behaviors, what is the nature and identity of social behavior circuits, how is the function of these circuits different in males and females and how are they modulated by the animal physiological status? In this lecture, I will describe our recent progress in using genetic, imaging, molecular and behavioral approaches to understand how the brain controls specific social behaviors in both males and females, and how areas throughout the brain participate in the positive and negative controls of specific social interactions. I will also describe how new approaches of single cell transcriptomics have enabled us to uncover specific cell populations involved in distinct social behaviors and the basis of their activity modulation according to the animal state.
