Unconventional Wisdom: Organic Reasons for Depressive Symptoms

As many readers will know by now, I think we need to be challenging and debating the logic that accepts “mental illness” as a valid concept.  I am concerned that our mainstream acceptance of the idea of “mental illness”, within our health and social care services, our mental health laws and our society, leads us to act in ways that, although well intentioned, cause bad consequences.  Ultimately this may result in more harm than good for people affected by the idea that experiences and actions can be diagnosed as "symptoms" of “mental illness”. 

Last Thursday, in our “Shaping Services Together” Conference, I think that we succeeded in furthering this debate in Powys.  With the help of Jacqui Dillon and Jo Mussen the morning started with us being asked to consider the following question:  

“Should mental health services be shaped by the question what happened to you rather than what’s wrong with you?” 

In this vein, I want to continue the theme from my last blog about organic reasons for psychosis by exploring organic reasons for depressive symptoms, again to try and make sure that:

In our drive to suggest that people are asked "what has happened to you" rather than “what is wrong with you”, let's not miss the question “is there anything physically/organically wrong with you?” 

Map of Medicine, which is the NHS system that claims to provide access to comprehensive, evidence-based guidance and clinical decision support, lists the following as typical symptoms of depression:

• an unusually sad mood that does not go away 
• loss of enjoyment and interest in activities that used to be enjoyable 
• tiredness and lack of energy 
• crying spells, withdrawal from others, neglect of responsibilities, loss of interest in personal appearance, loss of motivation 
• chronic fatigue, lack of energy, sleeping too much or too little, overeating or loss of appetite, constipation, weight loss or gain, irregular menstrual cycle, loss of sexual desire, unexplained aches and pains

A diagnosis of depression by a medical professional (in the case of depression, most often made by GPs) will be based on the number of these symptoms that you are experiencing/exhibiting, and whether you have experienced the symptoms for at least two weeks.

What are the known organic causes of these typical depressive symptoms?

Firstly let me try and clarify that by organic causes of depression I mean where the depressive symptoms are the direct result of an organic cause.  I do not include conditions where it is the actual coping with the organic condition, such as  cancer, dementia, heart disease, that results in us experiencing emotional stress and natural feelings of hopelessness, despair, loss of enjoyment and tiredness, feelings that could be diagnosed as “depression”.  Instead I am trying to find out about organic/biological conditions that cause a change in our physiological functioning that lead to the symptoms of depression that I  listed above. 

The Clinical Knowledge Summary from the National Institute for Health and Social Care Excellence (NICE) lists the following as organic reasons for depressive symptoms:

• Carbon monoxide poisoning   
• hyperthyroidism and hypothyroidism – state in which the thyroid gland production of thyroid hormones, thyroxine and triiodothyronine, is abnormal
• Rare side effects of prescription medication, such as: 
• antihypertensives used to treat high blood pressure 
• lipid-soluble beta used to treat a number of conditions including heart disease and high blood pressure 
• central nervous system depressants used to slow down brain activity prescribed for conditions including insomnia, muscle tension, pain, epliespy, anxiety and mood “disorders” 
• Opioid analgesics, generally uised for pain management 
• Isotretinoin primarily used for acne

However,as with my blog on organic reasons for psychosis, other organic reasons for depressive symptoms are to be found elsewhere on NHS sites.  These include:

• Cushing's syndrome, caused by very high levels of a hormone called cortisol 
• Hypercalcemia caused by abnormal levels of serum calcium concentration.  Also a complication of Pagets Disease 
• Hyponatremia where sodium ion concentration in the plasma is lower than normal 
• Diabetes when the pancreas does not produce enough insulin to maintain a normal blood glucose level, or your body is unable to use the insulin that is produced 
• Neurologic disordera such as Epilespy, Stroke, subdural hematoma, multiple sclerosis, brain tumors (especially frontal), Parkinson's disease, Huntington's disease, epilepsy, syphilis, dementias 
• Nutritional disorder such as Vitamin B12 deficiency, pellagra caused by a chronic lack of niacin (vitamin B3) 
• Other disorders such as viral infection and carcinoma

How do these organic/biological causes result in us experiencing depressive symptoms?

In many different ways it seems.  Some of the physical conditions listed above result in an imbalance of the hormones that we need to keep our bodily process working efficiently (e.g. thyroid hormones, insulin, cortisol).  When our hormone production or our ability to effectively use these hormones goes wrong, then a direct result can be symptoms of low mood, lack of enjoyment, tiredness, mood swings and lethargy.

Some of the conditions listed above cause damage to our brains in the areas that are know affect our mood so again the effect of this damage results directly in depressive symptoms. 

When someone experiencing depressive symptoms presents to a health care professional, what investigations will occur to determine whether there is an organic cause?

So back to the NHS Map of Medicine then.  It states that people presenting to health professionals with suspected depression may, “depending on the judgment of the clinical professional of the nature of their presentations”, expect to have medical investigations done to rule out an organic cause for their depressive symptoms.  The investigations are listed on this site but they include biochemistry tests, such as blood glucose, liver function tests, thyroid function tests and hematology tests such as full blood count.

Can depressive symptoms be misdiagnosed as a "mental illness" in this case “depression” when they are actually caused by organic/physical conditions? 

Unfortunately it seems that the answer to this is yes, again as it was with psychotic symptoms.  It is not difficult to find examples of organic problems being misdiagnosed as “depression” from across the academic world, the press and from people’s stories.    So examples where someone is diagnosed with "depression" and treated for this first, rather than the organic reason being found and appropriate treatment for the biological condition being given (e.g. removal of brain tumor, treatment for Hyperthyroidism).  

How often can the psychological symptoms we experience actually be explained by organic/physical/medical reasons? 

There is of course a lot of information about this on the internet but I really am not sure we know the definite answer to this.  It seems that a conservative estimate that about 10% of all psychological symptoms may be due to medical reasons, as this study suggests.   However the results of one study suggest that about 50% of individuals with a “mental illness” diagnosis actually have general medical conditions that are largely undiagnosed that may cause or exacerbate psychiatric symptoms.

So over to you again. Can you help me answer these questions?  Are they questions worth asking?  Tell me what you think ...

• Should mental health services be shaped by the question what happened to you rather than what’s wrong with you?
• In our drive to ensure that people are asked "what has happened to you" rather than “what is wrong with you”, lets not miss the question “is there anything physically/organically wrong with you”.
• What are the known organic causes of typical depressive symptoms and how do these organic causes make us feel “depressed”?
• When someone experiencing depressive symptoms presents to a health care professional, what investigations will occur to determine whether there is an organic cause?
• Can depressive symptoms be misdiagnosed as a "mental illness" in this case “depression” when they are actually caused by organic/physical conditions?
• How often can the psychological symptoms we experience actually be explained by organic/physical/medical reasons?

Psychiatry beyond the current paradigm

Last week Laura let me out of the office to go to this conference at Nottingham University organised by the Critical Psychiatry Network and Asylum Associates. It was perfect timing, as it meant I had the opportunity to see Jacqui Dillon speak just a week or so before she visits us here in Mid Wales for our own Shaping Services Together event on Thursday 19 September. 

I stayed for two of the three days and found all the speaker and workshop sessions immensely enjoyable. All stimulated some interesting and relevant debate, and I hope to pick up on some of the specific topics in future blog posts (for example, a workshop on an innovative Finnish approach called Open Dialogue, and Clinical Psychologist Steven Coles’ session on the dynamics of power).

Today, though, I just want to give an overview of the conference as a whole to give a flavour – and maybe tempt some local readers to pluck up courage to step outside the county and take part in an event like this – because there are increasing numbers which is great. I say “pluck up courage” because – I went on my own, I didn’t know anyone else before I arrived, and I was a little nervous about how it would be... two days surrounded by strangers at a huge unfamiliar venue (well everywhere outside Mid Wales seems vast)... and people who more than likely knew far more than I did about the subject – even the title of the conference was a bit off-putting! 

But five minutes after arriving at the venue I was deep in conversation with a woman from Wakefield about how difficult it is to find local groups in Yorkshire where people can share experiences about mental distress. And I was telling her about the peer support group based at Ponthafren in Newtown! (It’s a long drive though... better she sets up her own group in Yorkshire...)

The conference was promoted with this blurb: 
“Voices from within psychiatry who are seeking change are beginning to be heard. The Royal College of Psychiatrists’ leading regular publication, The British Journal of Psychiatry, recently carried a paper from the UK Critical Psychiatry Network entitled Beyond the Current Paradigm, which emphasises the importance of services and practitioners working with rather than upon those who seek their help. Perhaps unexpectedly, it received very little criticism from academics and peer psychiatrists.”

The first morning we listened to three keynote speakers, who started to explore this theme. Hugh Middleton (NHS Consultant Psychiatrist and also Associate Professor at the Nottingham University School of Sociology/Social Policy) began. He said that doctors of any sort only have authority to practice if there is clear evidence that it results in good rather than harm, and many now question whether psychiatrists fall into that category. The paper has “disappeared into a cloud of silence,” and Hugh and colleagues interpret that as “assent.” 

Hugh described how psychiatric drugs are trialled, summarising that all evidence to support the use of such drugs is flawed. The evidence around the benefits of psychological therapies is also possibly flawed – it is felt that if there is a positive outcome from such sessions this is down to the success of the supportive/nurturing relationship which is set up with the "client". Hugh said that we have to accept that sometimes something happens to people which profoundly disturbs them and/or the people around them, and that contemporary medicine provides no better solution than the demonisation or incarceration options of the past. He summed up his session by saying, “people want something different to what they get from conventional experiences. What is it? Let’s look for shared solutions.”

Jacqui Dillon followed, responding to the paper from “an activist position.” It is impossible to do justice to her presentation here, but some of the key points raised included:

• Biological (medical model) psychiatry is now trying to incorporate many of the approaches promoted by critical psychiatry groups, such as the impact of trauma on mental wellbeing. “But this is all about outcomes for psychiatrists – what about outcomes for ‘service users’?”
• It is assumed the doctors are the only ones able to do everything – psychological, social, medical – the lot. The message is: “you need us in charge.”
• Vested interests range through pharmaceutical companies, political parties to society in general, families and carers, some ‘service users’ and professionals.
• We locate madness in others – because it makes us feel OK.

So, what can be done? Some of Jacqui’s ideas to whet your appetite for next week:

• Reframe and reclaim ordinary language.
• Take a stand.
• Work in collaboration with people with lived experience.
• Help promote people’s voice.
• Lobby for change.
• Join a group with similar goals.

And what if we phased out psychiatry completely? What would the world look like then? Again, a few of Jacqui’s ideas:

• Develop non-medicated coping strategies.
• Create a range of self-help support (sharing books, setting up groups).
• Survivor-run crisis houses based on the Soteria model.
• Phase out mental health professionals and give basic skills to people – around active listening, being looked after, and sitting with people in distress.

This session was rounded off by Steve Trenchard, Chief Executive of Derbyshire Healthcare NHS Trust. His background is as a mental health nurse, and he said that he wanted to listen and co-produce solutions not yet found. There is “a need to focus on strengths and aspirations.” And he wants to develop ‘listening’ and ‘being with’ skills. 

Again, it’s very difficult to summarise in a short space, and Steve covered a massive range of areas in his talk, but at each point it seemed to me (and others listening as was discussed later) that his approach as a Chief Exec is extremely rare (even perhaps radical) and much needed. He considered new approaches to dementia care, schizophrenia, the use of physical restraint and seclusion rooms (including a pilot to close the latter) and our obsession with risk. He encouraged more self-control for people, which he considered the biggest factor in improving health, and spoke about the Expert by Experience programme – “no decision about me without me.”

Steve took inspiration, in part, from the past. He referred to The Retreat, set up in York in 1813 by a Quaker called William Tuke, a “supportive and healing environment” for people experiencing mental distress, as distinct from the inhumane and squalid asylums of the time. 

In Derbyshire it seems like things could be changing around services as professionals like Steve are listening to and responding to people’s experiences. I really hope that in Powys people who provide or commission mental health services can make that connection so that we see a shift here as well... And on that note, I look forward to continuing this discussion next Thursday at the Shaping Services Together conference at The Pavilion in Llandrindod Wells! See you there!

An update: Jacqui has kindly sent me her presentation and you can now read it here.

Unconventional Wisdom: Organic Reasons for Psychosis – Do we need to make sure that we don’t miss the question “is there anything physically/organically wrong with you”?

The Madness Of King George

I am on a bit of a mission at the moment trying to encourage people across Powys to explore whether the important question we need to be asking is:  

“Should mental health services be shaped by the question what happened to you rather than what’s wrong with you?”

In May 2012, Eleanor Longden spoke at an event we ran and raised this question. In a conference here in 2013 Jacqui Dillon helped us further this debate and you can here her speak here.  In April 2014 we ran a conference called Finding Meaning in "Psychosis" when again we were able to consider this question with the help of Lucy Johnstone, Sami Timimi and Eleanor Londgen

We are by no means the only ones debating this.  In fact, it seems that this question is resonating with may others and fuelling a debate across the world around the validity of mental illness diagnosis.  You can access some of this debate on twitter, my account is @powysmh.  

Whilst I for one am very interested in the impact that asking this question may have, I also wish to raise the need for caution.

In our drive to ensure that people are asked "what has happened to you" within health services, do we need to make sure that we don't miss the question “is there anything physically/organically wrong with you”? 

Psychotic symptoms (e.g. hallucinations, delusions, disturbed and confused thoughts), for instance, can be caused by illnesses, diseases and physical health conditions.  On the NHS Choices website there is a page that lists the medical conditions that have been known to trigger psychotic episodes.  These include Malaria, Syphilis, Azheimer's disease, Hypoglycaemia, Lupus, brain tumour and Lyme disease. But, this does not seem to be a complete list. I have also come across other organic causes that were not listed there.  B12 Deficiency, Porphyria, Wilson’s Disease, cerebrovascular disease can be found elsewhere on their site citing psychosis as one of the symptoms of these conditions . 

These organic/physical causes produce symptoms of psychosis for a number of reasons, for example abnormal enzyme production, brain damage, tumours, chemical element poisoning, abnormal hormone action, abnormal blood supply to the brain and vitamin deficiencies.  There are physical investigations and tests that can be done to determine whether someone is suffering from these conditions.
 
When someone first seeks help, or finds “help” thrust upon them, for psychotic symptoms, what investigations will occur to determine whether there is a organic/physical/biological cause?  

Diagnosed with syphillis

For adults, the Map Of Medicine Pathway based on National Institute for Health and Care Excellence (NICE) medical guidelines states that if someone presents to them with suspected schizophrenia, then doctors need to determine whether or not there are any physical/organic explanations for their symptoms.  

Worryingly, I think, the recently published (Jan 13) NICE guidelines for psychosis and schizophrenia in children and young people, does not seem to indicate that psychotic symptoms can have organic causes.  I could not find anything in the guidance, the supporting care pathway or the information for the public that indicated that psychotic symptoms could have organic causes.  I have to admit that I might be missing something, the guidance is very long, so I will be contacting NICE to ask.

Can psychotic symptoms be misdiagnosed as "mental illness" when they are actually caused by organic/physical conditions? 

Unfortunately it seems the answer to this is yes.  It is not difficult to find examples of misdiagnosis, where psychotic symptoms that have an organic/physical/medical explanation have led to people being given a mental illness diagnosis.  There has also been scientific work  that highlights where organic disease has been incorrectly diagnosed as mental illness (e.g. schizophrenia).     

How often can psychotic symptoms be attributed to organic/physical/medical explanation? 

I am not sure that we really have the information that would enable us to get to a definitive answer, I have found figures that range widely, from 5% through to 30%.   

So over to you. Can you help me answer these questions?  Are they questions worth asking?  Tell me what you think ... 

• Should mental health services be shaped by the question what happened to you rather than what’s wrong with you?
• In our drive to ensure that people are asked "what has happened to you" within health services, do we need to make sure that we don't miss the question “is there anything physically/organically wrong with you”?
