Welcome to the website of author & composer, Patrick Ussher.

Postural Orthostatic Tachycardia Syndrome (POTS) is a debilitating and often disabling autonomic illness that affects at least one million people worldwide. In the book, I argue that the condition's cause stems from a misfiring in the limbic system in the brain and that this can be corrected through neuroplasticity. I had this illness some years ago but recovered from it (although I subsequently developed ME/CFS after several years of good health, unfortunately).

A comparison of two philosophical ways of life, Stoicism, the ancient Greco-Roman philosophy, and Buddhism as practised in the West. Although there is no direct influence of the one on the other, I argue that both philosophies share many similarities and could also learn from each other. This book stems from research I did during my MA at the University of Exeter. This book has been featured on Shepherd.

This is a new edition of The Pink Ribbon Path, originally written by my late mother (Mary Redmond-Ussher). It is spiritual path for those facing serious illness, originally compiled by my mother during her six years with breast cancer. This new edition includes additional writings by those touched by my mother's original book as well as an introduction by myself on how I saw my mother live during her years of illness. I spoke about the book and my mum on Irish radio station, RTE.

In 2012, I founded the Stoicism Today blog, which I then ran for four years. These two books are compilations of some of the best pieces from that time. The Stoicism Today project, now known as Modern Stoicism, is a collaboration between academics and psychotherapists working on developing Stoic resources for the modern-day. I was part of the team from 2012-2016. Every year, the project runs 'International Stoic Week' which is followed by thousands of people worldwide.

This is a hypothesis in which I challenge the condition known as 'psychogenic water drinking' (aka 'Primary Polydipsia'). This condition is currently regarded as involving the overconsumption of fluids as a result of mental illness. However, the cause is also acknowledged as unknown. In this book, I suggest that the typical clinical presentation of dilute urine, hyponatraemia and unquenchable thirst can mainly be explained with reference to the low blood volume, and the thirst this creates, in illnesses such as ME/CFS, POTS and Long Covid.
