Introduction

Bipolar, otherwise known as manic depression, now exists largely within common consciousness and understanding, thanks to high profile stigma-busting publicity.

Characterised by episodic shifts in a person’s mood (between manic and depressed states), as well as their energy and activity levels, which can significantly impact their daily functioning, bipolar is estimated to affect 1% of the population across the lifetime. However, this figure rises to over 4% if you include those who experience more than one episode of sub-threshold manic (or ‘hypomanic’) symptoms.

What we know already

Anxiety is unsurprisingly common in people living with bipolar. Similarly, substance abuse is frequently reported.

Whilst there is no cure, there are several well-established treatment options. Bipolar is usually treated using mood-stabiliser, atypical anti-psychotic and/or antidepressant medications, alongside psychological, and diet and lifestyle interventions. We know, for example, that bipolar can be well managed using regular monitoring of mood, keeping stress levels to a minimum, and ensuring good sleep.

Areas of uncertainty 

Like many mental health difficulties, the precise causes of bipolar are unknown, though they are likely multi-faceted. Research shows that you are more likely to develop bipolar if it exists in your family. Although most children with such circumstances will not go on to develop bipolar, there appears to be a strong genetic component. Environmental factors such as stressful life events are also thought to play an important role.

Recent research suggests that, whilst it appears beneficial to treat bipolar with psychological interventions, the heterogeneity of the evidence makes it difficult to decide which treatments (such as CBT, Mindfulness etc) work best.

What’s in the pipeline?

Large-scale studies, such as the U.S-based Bipolar Disorder Phenome Database, are seeking to better understand the complex genetic picture.

Advances in brain imaging will no doubt provide rich information regarding the neurochemical and neurostructural profile of bipolar. Similarly, technological advances are enabling more sophisticated ways of promoting self-management in conditions such as bipolar.

Cardiovascular screening for people with severe mental illness: still missing the full picture

Featured

Only 35% of people with severe mental illness received all six cardiovascular risk factor checks within one month in this UK primary care study. Financial incentives temporarily increased comprehensive screening but effects were uneven and short-lived. Young men of non-White ethnicity were most likely to miss screening, highlighting persistent inequalities.

Rapid weight gain after SMI diagnosis, but why so few referrals for support?

Medical scales

A 15-year analysis of UK primary care records showed steep and sustained weight gain after an SMI diagnosis, especially among younger adults and people prescribed antipsychotic medication. Yet very few received referrals for weight-management support, raising important questions about practice and policy.

High misdiagnosis rates between bipolar and major depressive disorder cause real harm to patients and services. This new neuroimaging study tested whether brain connectivity and machine learning could do a better job of telling the two apart, with interesting but limited results.

People with severe mental illness are more than twice as likely to die from respiratory disease than those without. This new systematic review highlights the scale of the problem and why action on public health and social inequality is just as vital as stop-smoking advice.

Should you start metformin whenever you start antipsychotics?
