Clams and coffee for a good morning

I like B vitamins and caffeine, that is a good combinations. And a bit of carbs. Coffee, clams, and oatmeal bar with dates makes a good breakfast. I don’t know the mechanism, but I am finding that coffee helps me to be more present in the moment with fewer anxious thoughts about the future. Going back to coffee was not a random idea, there are several studies in regards to the use of caffeine for treatment resistant OCD. By the way, OCD is not just about washing your hands multiple times or checking five times that you locked the door. The worst aspect of if it is how your mind is affected by unwanted and intrusive thoughts. There are infinite types of OCD, it can impact on any thought, on any subject, on any person, on any fear, and frequently fixates on what’s important in a person’s life. For example, if religion is important to someone, OCD fixates on unwanted intrusive thoughts around religion, perhaps making the sufferer believe their actions/thoughts will offend their god. Another example is if someone begins a new relationship, OCD can make a person question that relationship, their feelings, their sexuality resulting in almost constant rumination, perhaps with the sufferer worrying that they may be misleading their partner.

Obsessive thoughts are what happens when you just want to go for a walk in the forest. It’s a warm day, finally summer, you are surrounded by colourful moss on intriguing rocks. You want to wander around observing the details of nature, but your mind is fixated on the thought that there is no point. There is no god, therefore our lives are meaningless, and there is no point of this wandering. Or the thought is – I don’t have a child, so I need to work on getting a family. And then you feel that because you haven’t achieved this goal, you will be punished for wandering around the forest. You should be punished for any enjoyment as those are not focused on the goal. You need to solve the problem at hand, you need to act now, you need to think through the plan. And it goes on.

B vitamins are essential for creating dopamine, epinephrine, serotonin, and myelin. They also help the mind focus, help hemoglobin hold oxygen and lower cholesterol. Vitamin B is essential to good health. It is also used for energy production in the human cells. B vitamins help convert food often consumed as carbohydrates into fuel. They also help the nervous system function properly. B vitamins are water-soluble, which means that they are easily dissolvable in water and easily excreted out of the body via urine output. As a result of this type of vitamin that can be dissolved in water, individuals cannot overdose on them because all excess will simply be excreted.

Solubility – Solubility is defined as the maximum quantity of a substance that may be dissolved in another. How a solute dissolves depends on the types of chemical bonds in the solute and solvent. For example, when ethanol dissolves in water, it maintains its molecular identity as ethanol, but new hydrogen bonds form between ethanol and water molecules. For this reason, mixing ethanol and water produces a solution with a smaller volume than you would get from adding together the starting volumes of ethanol and water.

When sodium chloride (NaCl) or other ionic compound dissolves in water, the compound dissociates into its ions. The ions become solvated or surrounded by a layer of water molecules.

Thiamin is vitamin B1, it is essential in carbohydrate metabolism and neural function. It is water soluble and is absorbed through both active transport and passive diffusion. Not being endogenously synthesized, the only available source of thiamine is dietary (beef, poultry, cereals, nuts, and beans). In the human body, thiamine-rich tissues are skeletal muscles, heart, liver, kidney, and brain. Thiamine serves as a cofactor for a series of enzymes in different metabolic pathways and is required for the production of ATP, ribose, NAD, and DNA. Thiamin plays a key role in the maintenance of brain function. Thiamin diphosphate is cofactor for several enzymes involved in glucose metabolism whereas thiamin triphosphate has distinct properties at the neuronal membrane.

Thiamin metabolism in the brain is compartmented between neurons and neighbouring glial cells. Thiamin deficiency is commonly encountered in severe malnutrition associated with chronic alcoholism, HIV-AIDS and gastrointestinal disease where it frequently results in Wernicke’s encephalopathy (the Wernicke-Korsakoff syndrome).

In developed countries, the predominant use of industrial food processing often depletes thiamine content along with other vitamins and nutrients. An increased consumption of processed food in the form of simple carbohydrates, not supplemented with adequate levels of thiamine, has been named “high calorie malnutrition”. As thiamine is a key factor in the metabolism of glucose, an increased carbohydrate intake will proportionally increase thiamine’s dietary demand. Heavy consumption of tannin-containing or food rich in caffeine, theobromine, and theophylline (such as those present in coffee, chocolate, and tea, respectively) can inactivate thiamine, thereby compromising the thiamine status. Other risk factors that increase the likelihood of insufficient thiamine intake include aging, economic status, eating disorders, medical conditions affecting the gastrointestinal tract, subjects receiving parental nutrition, bariatric surgery, diabetes, and alcohol abuse.

Thiamine deficiency might cause brain tissue injury by inhibiting brain energy utilization given the critical role of thiamine-dependent enzymes associated within glucose utilization. This is supported by the significant rate of thiamine uptake by the blood–brain barrier emphasizing the high brain demand for thiamine and the need for its supply to sustain adequate brain functions.

Throughout the digestive tract, dietary proteins get hydrolyzed, releasing thiamine. In the intestinal lumen, alkaline phosphatases catalyze the hydrolysis of thiamine-phosphorylated derivatives into free thiamine.

There are cases of psychosis resulting from thiamine deficiency.

Case 1 – a 63-year-old woman with thiamine deficiency who showed auditory hallucinations, a delusion of persecution, catatonic stupor, and catalepsy but no neurological symptoms including oculomotor or gait disturbance. Her thiamine concentration was 19 ng/mL, only slightly less than the reference range of 20-50 ng/mL. Her psychosis was unresponsive to antipsychotics or electroconvulsive therapy, but was ameliorated by repetitive intravenous thiamine administrations at 100-200 mg per day. However, one month after completing intravenous treatment, her psychosis recurred, even though she was given 150 mg of thiamine per day orally and her blood concentration of thiamine was maintained at far higher than the reference range. Again, intravenous thiamine administration was necessary to ameliorate her symptoms. The present patient indicates that the possibility of thiamine deficiency should be considered in cases of psychosis without neurological disturbance and high-intensity T2 MRI lesions. Also, this case suggests that a high blood thiamine concentration does not necessarily correspond to sufficient thiamine levels in the brain. Based on this, we must reconsider the importance of a high dose of thiamine administration as a therapy for thiamine deficiency.

Case 2 – Mr A, a 40-year-old man, was transferred to our drug and alcohol dependency clinic after admission to the emergency department of a general hospital. He had a 25-year history of regular alcohol consumption (2 bottles of wine and 3–4 bottles of beer per day recently). Notably, he gradually increased his alcohol intake. His family stated that for the last 2 years he started his mornings with his usual “eye opener,” and he had not been eating enough or regularly. They also described periods of alcohol withdrawal, which resulted in delirium tremens symptoms such as confusion and auditory and visual hallucinations. He presented to the emergency room with forgetfulness, difficulty walking, falling down, urinary incontinence, losing his belongings, and not being able to recognize where he was or the current date. His family also reported that he had been telling incongruent stories that never seemed to have happened.

Mr A was diagnosed with Wernicke-Korsakoff syndrome according to DSM-IV diagnostic criteria, and diazepam detoxification, rehydration, and thiamine repletion therapy were started. He had no signs of alcohol withdrawal in the clinical follow-up. He was administered intravenous (IV) 2,000 cm3 of 5% dextrose and 1,000 mg thiamine hydrochloride. This regimen was administered until the fifth day of treatment since gait ataxia and restriction of eye movements were no longer prominently present. On the sixth day of treatment, the IV thiamine was replaced with 100 mg oral thiamine. Within the third week of the treatment regimen, his gait and postural ataxia improved and his orientation to time, place, and person was intact. By the fourth week of treatment, he was able to find his way around the city and back home when he was on home leave for 2 days. However, it was observed that it took him longer to remember his past experiences when questioned. He was discharged 41 days after his hospitalization. He had no significant mental symptoms apart from a minimally longer reaction time and minimal impairments in current memory, although he still had difficulty in tandem walk and a minimal nystagmus in his neurologic examination at discharge.

Neuropathology of Wernicke-Korsakoff syndrome is characterized by gliosis and microhemorrhages specifically in the periaqueductal and paraventricular gray matter, atrophy in the mammillary bodies and thalamus, and volume deficits in the hippocampus, cerebellar hemispheres, pons, and anterior superior vermis; however, anterior thalamus, mammillary bodies, and the mammillo-thalamic tract are reported to be related with later memory impairment and Korsakoff syndrome.

Active transport – the movement of molecules across a membrane from a region of their lower concentration to a region of their higher concentration—against the concentration gradient or other obstructing factor.

Passive diffusion – is a movement of ions and other atomic or molecular substances across cell membranes without need of energy input. Unlike active transport, it does not require an input of cellular energy because it is instead driven by the tendency of the system to grow in entropy.

Hyrdolysis – any chemical reaction in which a molecule of water ruptures one or more chemical bonds.

Alkaline phosphatase – an enzyme that liberates phosphate under alkaline conditions and is made in liver, bone, and other tissues.

Gliosis – is a nonspecific reactive change of glial cells in response to damage to the central nervous system (CNS). The glial cells surround neurons and provide support for and insulation between them. Glial cells are the most abundant cell types in the central nervous system. The four main functions of glial cells are: to surround neurons and hold them in place, to supply nutrients and oxygen to neurons, to insulate one neuron from another, and to destroy and remove the carcasses of dead neurons (clean up).

Microhemorrhages – cerebral microhemorrhages, best visualized by MRI, result from rupture of small blood vessels in basal ganglia or subcortical white matter.

Mammillary bodies – the mammillary bodies are part of the diencephalon, which is a collection of structures found between the brainstem and cerebrum. The mammillary bodies are best known for their role in memory, although in the last couple of decades the mammillary bodies have started to be recognized as being involved in other functions like maintaining a sense of direction.

Misdiagnosed with schizophrenia for a year. Later on received the correct diagnosis of autoimmune encephalitis (Hashimoto's Encephalitis) in April 2017. This is me trying to understand this autoimmune disease, what led to it, and why it took so long to diagnose.
