Depression is the most common reason to be admitted to a psychiatric unit in Ireland, with females being 19% more likely to have depression as their reason for admission to a psychiatric unit than males. This is not unique to Ireland, worldwide women are affected more by depression than men. In fact, globally, more than 300 million people of all ages and gender suffer from depression and according to the World Health Organisation, depression is the leading and growing cause of disability worldwide.
The above map indicates that in 2015, the most depressed country in the world was Afghanistan, where more than one in five people suffer from the depression. The least depressed is Japan, with less than 2.5 percent of the population diagnosed with depression. It is not surprising that war, conflict, oppression, disease epidemics, famine and serious public health issues increase the rate of depression and feelings of hopelessness. The long term burden of depression or the number of healthy years a person loses because of depression or a depression-related premature death is especially notable in countries where relatively recent conflicts have taken place e.g. countries such as Palestine, Afghanistan, Honduras, Eritrea, Rwanda, Botswana and Croatia. However, other factors such also play a part in the susceptibility to depression and the depression burden to health resources. Unemployment, low incomes and high income inequality are also linked with high depression rates. Age too plays a part with people between 16 and 65 being most susceptible to depression and a reduced risk at the extremes of life. It may be that the growing rates of depression globally are also related to the dominance of the 16-65 year old age group. However, none of these give a strong reason why countries like Holland were also high on the scale for depression.
In the past depression like symptoms were often known as melancholia and melancholia was the second most likely reason to be admitted to St Finan’s Hospital, Killarney in the early 1900s. However, it is difficult to directly correlate melancholia with present day depression as the term melancholia was also used to described other conditions such as senile melancholia and delusional melancholia which may fall into different categories in present understanding of mental illness (eg senile melancholia may possible be Alzheimer disease or dementia and delusional melancholia may be a form of psychosis).
According to the Irish Research Board, the male population in psychiatric units in Ireland was slightly higher than females in the early years of this decade. While women were more likely to be diagnosed with depression or personality and behavioral disorder, men were more likely to have schizophrenia or alcoholic disorders as the cause for admission.
Behind the Walls is a two part documentary made by journalist Mary Raftery for RTE which covered the historic treatment and abuse of patients in Irish psychiatric institutions or asylums. The documentary gives an insightful and sad account of the stories of pain, abuse, neglect and dis-empowerment experienced by patients in Irish Mental Hospitals. These institutes often became dumping grounds for Ireland’s unwanted. People who were outcast, the unwanted, the different, people that did not confirm, spirited people and people who questioned authorities. There was too, people who struggled with life and its demands, people who had clear mental illnesses, were trying to cope with abuse or were suicidal and melancholic (what we would called depression today). There is no doubt that the admission criterion, definition and diagnosis for insanity was very broad and appears to be easily manipulated. The documentary highlighted that one causative reason was ‘husband in California’. Certainty with my research on the St
Finan’s archives, I have come across an equally broad criterion for admission (See Figure 1 below) and saw a similar rationale, such as ‘resident in the USA’, ‘husband in England’ as well as ‘seduction‘, ‘married life‘ as well as physical illness like ‘influenza‘ or ‘anaemia‘.
The archival case books and other material from different old psychiatric institutions are regarded as damning documents that give an unique insight into the human condition. Indeed, from the first day that I gained access to the archives of St Finan’s, I was aware of the enormity of responsibility in both reading and telling the stories of the thousands of people who have passed through its doors.
Over the next while, I will be compiling some of the case stories (whilst maintaining confidentiality) and am going to share the insights that I have come across. Already I think of a young 19 year old woman, who had to go to the Killarney Workhouse to give birth to her child. She was unmarried, without income, and apparently without family or family support. Soon after giving birth, she returned to the lane-way where she had previously been living and came across another young woman, who it appears, was a source of rivalry. In a fit of jealousy, she approached the girl and threatened her with a knife. Subsequently, she was apprehended and taken to the asylum. Another case involved a young spirited girl in her mid- twenties, who tried to get away from her overbearing mother. She was found at the railway station, with her bags packed, ready to leave. When confronted at the station, she resisted returning with her mother. Again, she attempted to get away and her mother, beckoned people to help. The young woman fought three or four people, including the police, that tried to to hold her down. Instead of getting away, she was gathered by the group and forcibly brought to the asylum. After being admitted, both females, explained their predicament; the former, acted in a fit of jealousy (possibly in relation to the father of her child starting up a new relationship, the latter, wanted to get away and lead her own life). In the case books for both patients, behavior was described as normal with no signs of mental illness. However both stayed inside the asylum walls for a length of time.
Going back to the documentary, the decades of individuals forgotten in institutions is a story that needs to be told. A lot of the programme focuses on the institutions in the 50s and 60s when Ireland’s huge institutional system was operating at a never ending expanding size and scale. Some of the leading experts on the history of Irish psychiatric institutions discuss its legacy but its the stories of its patients and survivors that give insight and give the human connection. One wonders about the size and scale of admissions and why as a society we felt the need to collaborate in locking away so many of our people.
Early asylums developed from prison system. Jails and workhouses would have lunatic sections and when the Killarney District Lunatic Asylum first opened in 1852, the majority of the initial patients were from the Tralee jail or the Tralee and Killarney workhouses. According to Professor Kelly in his book Hearing Voices: The History of Psychiatry in Ireland, some of the procedures in the asylums came from prisons system rather than a healthcare standpoint. This resulted in some patients being chained up, while others were restrained in straitjackets. According to the Inspector of Lunacy in the mid 1800s, some asylums were particularly bad. In Limerick asylum, patients were chained with their hands placed under their knees so that they were unable to stand up resulting in a permanent disability and an inability to stand up straight.
The history of mental healthcare has shown that how we treat the mentally ill in our society is far more to do with how society treats the vulnerable than any other area of social care or medicine. In 1907 at the Richmond asylum, one third of all admissions were directly from the workhouse across the road. Brendan Kelly points to his time working in the Mater in the last decade, noting that one third of psychiatric assessments in the emergency department were homeless people. Ireland has a significant problem with suicide and some sources state that mental health issues have risen over the last twenty years. A warning that the fast changing pace of the 21st century may be a new challenge to mental healthcare.
Some illnesses can trigger stress and mental illness. High or low thyroid levels can affect mental health causing manic mood or depression respectively. Pernicious anaemia (B12 deficiency) is also linked to neurological and mental illness. But have you heard about how the time of the year that you are born, your exposure in the womb, catching an infection, being inflammed, and your gut flora can also contribute to mental illness?
This 1 percent who globally experience schizophrenia have another pattern which is called the birth month effect. People born in winter or early spring are more likely than others to become schizophrenic later in life. It is a 5 to 8% increase and its a pattern that is also seen in people with bipolar disorder or multiple sclerosis.
The brain is a complex organ that is very greedy for energy, and factors that affect that energy supply can have long-term consequences on the neural connections of the brain. Fuller Torrey, director of the Stanley Medical Research Institute in Chevy Chase, Maryland, is an advocate of the infection hypothesis and believes that an infection or fever is the trigger for schizophrenia. The infection theory was around in the late 1800s and early 1900s. Adolf Meyer was one of the most influential figures in psychiatry in the first half of the twentieth century who stated that psychiatric illness is the result of chronic infection akin to what patients with high fevers sometimes experience such as delusions and hallucinations. His theories gathered a lot of followers and some psychiatrists used to pull out rotten teeth or tonsils of their mentally ill patients in the search for a cure. However, by the 1930s, as the rest of the medical world focused on infectious agents as the cause of disease, the psychiatric profession moved away from it. Instead the emerging pharmaceutical and biological approach was fostered.
Meyer’s theories are gaining some interest over the last decade. There is scientific evidence how certain infections of the brain such as Toxoplasma gondii (one of the most common parasites in developed countries) can result in symptoms that mimic psychiatric conditions. Borna disease virus, Epstein-Barr and certain strains of herpes, including varicella zoster, the virus that causes chickenpox and shingles can also trigger mental illness like symptoms.
A study that evaluated over three million patients record in Denmark discovered that a history of serious infection was associated with a 62% increase in later developing a mood disorder, including depression and bipolar disorder. Furthermore, multiple studies have also linked elevated markers of inflammation with depression. An interleukin 1, part of the immunity’s fight against infection is known to cause symptoms of depression. Additionally, depression scores correlated with an inflammatory marker known as C Reactive Protein (CRP), a protein which is high in inflammatory conditions such as Cardio vascular disease and inflammatory bowel disease. Another Danish study published in The Archives of General Psychiatry, demonstrated that low-grade systemic inflammation can cause depression. Moreover, they discovered that even in healthy individuals, an elevated CRP was associated with a higher risk of depression. This leads to the question is depression an inflammatory disease? And if so, is there a culprit triggering the inflammation? Some anti-depressant medication can also decrease the inflammatory mediators, indicating a relationship between the neural firing and inflammatory immunity response. Not surprising really when you take into account the complex interaction of the nervous system and our immunity. In fact, infectious agents such as pathogens acting directly on the central nervous system, may result not only result in psychiatric symptoms, but also trigger autoimmune activity, resulting on the body’s immune system attacking itself. The 2015 discovery of the central nervous system lymphatic system reported in Nature, is challenging the aetiology of neuroinflammatory and neurodegenerative diseases associated with immune system dysfunction. The study states that the malfunction of the meningeal lymphatic vessels could be a root cause of a variety of neurological disorders in which altered immunity is a fundamental player such as multiple sclerosis, Alzheimer’s disease, and other forms of mental illness and neurological disorders.
Science is beginning to connect the dots of the relationship between inflammation, immunity, lymphatics and neurological system. We have known for a long time about other neurological diseases and infectious pathogens. For example, its well known that 10 to 30 years after the initial infection with the sexual transmitted bacteria known as Treponema pallidumsyphilis, neurosyphilis can occur resutling in neurologic and neuropsychiatric disease, previously known as General paralysis of the insane. Neurosyphilis can cause a wide range of symptoms such as memory difficulties, delusional thinking, and grandiosity which has been associated with mental illness. In the asylums of the past, before the discovery of antibiotics, patients with this condition were a frequent feature of the asylum.
Our immune system is an evolutionary old part of our physiology and it works with homeostasis to fight infections, and ensure genetic survival. The immune system with its homeostasis co-worker, cortisol (often called the stress hormone but it really is so much more), does not distinguish between the sources of our inflammatory provocation. It will activate a stress response regardless if it is an infectious pathogen, sleep deprivation, physical, mental or emotional stress, abuse, grief or nutritional deficiency. Hence an immune response has the capacity to activate a mental health challenge for weeks, months or years. There is some research that also queries that this inflammatory provocation can have effects on the growing foetus in the womb.
As new born babies, we are relatively sterile from microbes when we are born. By the time we are adults, we have, on average, four pounds of gut microbes, and the combination is more unique to an individual than their own DNA. There is also increasing evidence that gut microbes effect the development and brain biochemistry. Recent work studying communication between the brain and the gut have also identified a functional link between gut microbiota and brain function, with particular attention to depression and anxiety. Our bacteria development early in life is needed for early brain development, and perhaps an imbalance might be a predisposing factor for a number of brain disorders.
So finally, to summarise, infection, could work with genetics, psychosocial factors and our diet and microbiome to influence immune and inflammatory activity and, in turn, our risk of mental illness.

St Finan’s Hospital closed its doors in 2011. Since then the hospital has been unused. I was trying to gain access to the hospital to photograph the internal structures and get a feeling for the institute. Unfortunately, at present, I have not been able to get access. However, through sites such as Abandoned Ireland, I came across some photographs taken in 2011 and have been granted permission by the photographer to share on this site.

So have you heard how some creativity is akin to insanity? Well, scientists who have been studying how the mind works, have discovered that the fMRI (brain scans) reveal strong similarities in the cognitive pathways of highly creative people and those with schizophrenia. Both lack the ability to inhibit certain significant receptors used to filter and direct thought; allowing them to see different perspectives of the world.
However, for some, this uninhibited pathway, which enables an ability to think outside the box leads to a psychiatric pathology, schizophrenia, which affects about 1 percent of humanity globally.
