Schizophrenia as a Disorder of Disorganized Focus of Attention ONLY.

Schizophrenia as a Disorder of Disorganized Focus of Attention ONLY. 

Schizophrenia is THE psychiatric condition with variable manifestations involving all the major areas of a mental state examination, appearance and behaviour, thoughts and speech, cognitions, perceptions, mood, and most commonly, insight or reality-testing. Studies have long proposed schizophrenia being related to impaired regulation of attention; we propose a model explaining the entire range of manifestations as the result of a disorganized focus of attention. 

Explaining delusions

The cognitive model of depression proposes that patients with dysfunctional beliefs maintain these because of their selective attention to evidence that confirms these beliefs and their tendency to ignore the evidence against it. In the most severe cases, these dysfunctional beliefs may progress to delusions in which case they absolutely do not attend to evidence against their delusional beliefs and are preoccupied with the evidence and thoughts that confirm their belief system. In the case of schizophrenia, this regulation of attention is not mood dependent, it is disorganised but persistent.

Autochthonous Ideas

Described as cognitive interference, the intrusive thoughts are often influenced by environmental cues (for example, thinking about alternative hypotheses of schizophrenia when reading a new one) or mood state (as in the case of anxiety or mood disorders where patients are preoccupied with worries or sad memories). The cognitive theory of obsessive-compulsive disorder proposes not the occurrence but the obsessional patient’s inability to control intrusive thoughts, which is the intrusive thoughts are normal in humans, but the inability to shift attention from them is not.  A sudden delusional idea in patients with schizophrenia strongly favours the disorganized focus of attention in these patients. Objectively, ideas do not COME to mind, patients do not DEVELOP them, instead of the mind shifts (the focus of) attention to ideas. 

Explaining the Disorganised Behaviour and Speech

The most obvious evidence for a disorganised focus of attention in patients with schizophrenia is their disorganised speech and thoughts. Patients with the loosening of the association are said to “jump from topic to topic with now link between them.” We propose their disorganised focus of attention causes them to switch topics, much less influenced by environmental cues unlike in patients with mania, who exhibit a flight of ideas influenced by their distractibility and abundance of ideas. Patients exhibiting self-laugh or self-talk are not able to attend to the environment, despite being fully conscious. Patients with loss of self-care or avolition, in general, are not able to attend to their needs.

Explaining Mood

The mood is highly intervened with the focus of attention both influencing each other. A patient with anxiety focuses attention on anxiety-related cues, a patient with infectious joviality focuses attention on cues of pleasure. In patients with schizophrenia, there is often a disconnect between the mood and their attention. A patient with incongruent affect may be describing (attending to) depressing events while smiling. 

Explaining Hallucinations

Affect illusions are mild perceptual abnormalities, for example, a person preoccupied with fears walking in the dark may misperceive a bush for a monster. Their perceptual abnormalities occur along a spectrum of severity. Patients with delirium may exhibit any of these, for example in a state of fear, misinterpreting a stethoscope for a snake or seeing giant scorpions on the wall.  

Interlinking with Biology

Attention, executive control of attention, cognitive interference are higher cognitive functions primarily ascribed to the prefrontal cortex. Dopaminergic medications, as in patients with attention deficit hyperactivity disorder, help sustain their attention. Hyperdopaminergia favours the persistence of attention to the delusional ideas and the hallucinatory voices in patients with schizophrenia unlike in patients with mood disorders in whom the delusions and hallucinations are fleeting.

Post-Traumatic Stress Disorder: Sample CASC

So, I have been asked by your GP to have a chat with you because you are having some difficulties in judging. So, as far as I know, you have, you were in an accident. A few months ago and since then you've been having some difficulties. But if it's okay, I'll let you explain what led you to come in here already.

Yeah, I just had an accident about six months ago. And ever since then, I just can't get out of my head.

was it was a serious accident?

Yeah, it was it could have been, you know, the car was all messed up in a way you

know to sort of concussion

to split a whiplash room in the car was really hard.

I can see where you're getting a bit anxious even talking about it. If you find questions difficult to answer It's okay, we can move on. And you can take your time, too, if you're feeling anxious. So you had this unfortunate accident you said that, although you will not seriously injure the car was quite badly damaged, and you make the most depending on how long you have to be in the hospital.

Just a couple of days.

Yeah.

And you mentioned the competition, did you suffer any kind of memory loss or any confusion? And so this happened, about six months ago. And when did you experience the problems in your programs?

In the beginning, it was normal, you know,

it was really, really horrible.

But it just keeps going on. It just seems to get worse. Get rid of it. It's just taken over my life now.

Difficult. And so, can you describe what has been happening, what sort of experiences have you been to. Have you been experiencing?

And the newest thing is a sort of the last one, really I just sort of. I'll be at work or be out with your friends or anything, I just start hearing. Like screeching tires or metal.

This off. I can hear it and then it's like it's happening all over again. I just feel completely sort of paralyzed. So you've got a couple of minutes. It just seems like a lifetime.

Sounds really scary and some people, when they experience, have this kind of experience they also sometimes have nightmares of these incidents. And is it quite frequent the nightmares?

Yeah, so most nights really seem to get worse. Okay. But now it's sort of every night and it's just sort of stuck in the same thing I'm just reliving it up to where it happens and it's often what we find is a traumatic incident like that, avoid situations that might lead to a similar thing, avoid doing the things that happen on the day of seeing that happen in your case.

And now I'm going to drive with anybody else in the car.

Right. My friend.

I just keep thinking that I could have killed her.

Are you able to drive with no kind of emotional

Avoid at all costs, but I need to keep working. If I can avoid doing anything more than I have to do. I'm late every morning because it's just such a workout to get myself in the car to go.

And are you doing anything to deal with all these problems? And when you say drinking is more than community drink after the incident. Did you use to drink before?

I sort of had a glass of wine after work, but now it's just so I just have another one and then another one. I'm just so worried about going to sleep. So I just, I just have a couple more drinks and it just helps me. It helps me get to sleep.

How much do you drink?

Probably. Probably, um, maybe a bottle of wine.

So asking this, but you won't be using any other substances, middle class, here. So, your drinking has gone up You said that you were feeling quite anxious and agitated. Do you also find that you have become a bit more snappy, irritable, with people?

He says I'm a different person now. He thinks I'm just angry all the time. I get mortgage irritated, the normal, a film just got shorter views than I did before.

And you also are quite easy to be always vigilant about what's going on around you.

You know, if I have to sit in the car with my boyfriend's driving to somewhere. I'm constantly on edge I'm looking around for other cars and any sort of hazards, constantly jumping or saying oh slow down or things like that. Yes.

I think all of this must be quite draining on you, how do you say your mood has been in the last few weeks.

I just feel so tearful all the time. On the verge of crying because I just seem so frustrated, but it's still, still going on.

Do you have any happy times in between the lives of many you're doing anything specific?

that already enjoy much,

Because you feel constantly alone and not enjoying things as well. What would you say your energy levels are like

guess just because on the edge all the time we're just taking a lot out from this what

Do you find the most interesting things that you used to enjoy? And you mentioned trying to sleep. Because you are afraid of sleeping, you have been drinking the evening. But when you go to sleep. Go to sleep.

Wake up a lot. Having these dreams gets to a point. So it's all happening again with the car, and then it gets to a point and then a shock. Wake up and then go back to sleep and it just happens.

So good focus on being able to look after yourself. Eat. Look after food and diet.

And since you've been feeling stressed, I mean, do you find that you've had any specific negative thoughts towards where you're not wanting to live anymore or felt like harming yourself or something.

Oh yeah, I don't, I don't want to live like this anymore. I don't kill myself, that's

Been asking lots of questions and you've been very patient with me Thank you very much. I need to speak to my team, and especially the psychologists in my team, because from what you're paying, what you're doing. Today, it seems like you are experiencing symptoms of post-traumatic stress disorder, commonly known as PTSD, and your concern appears below. So, I would speak to the Secretary of State and see if what the missed approach would be because we need to have. We go for psychological therapy first or try combination therapy and medication. But we have a discussion with the team and arrange another appointment for you so I can discuss more what the plan will be.

Lithium

 

Lithium

FAQ 01

What are the indications for lithium?

We use lithium in the prophylaxis and treatment of mania, prophylaxis of bipolar disorder, as an augmentation strategy for patients with treatment-resistant depression.

What are the common signs of lithium toxicity?

Thirst, polyuria, memory problems, tremor, weight gain, tiredness, diarrhea. Cognitive dysfunction is the most common symptom that leads to non-compliance. Side effects are dose-related.

What is the concentration at which toxic effects reliably occur?

Toxic effects reliably occur at 1.5mmol/l but toxic effects can occur at MUCH LOWER LEVELS in many patients, especially in older patients, systemically ill patients, and in use of alcohol or other CNS active meds

What are the two systems lithium causes the most damage to?

Thyroid and kidneys

What are the differences between the brands of lithium?

There are differences in bioavailability, and recommendations are to keep to the patient on the same brand. If it is necessary to change formulations, lithium levels must be monitored closely until a patient reaches a steady state.

What are the distinct forms of lithium found in different formulations?

Tablets have lithium carbonate; liquid has lithium citrate.

How is lithium administered, timing-wise?

We give it as a single daily dose at night. 

When should blood for serum lithium estimation be taken?

12 hours after the last dose. IF you're on liquid then you take the blood before the morning dose.

What can cause increased lithium concentrations?

A low-salt diet, diarrhoea, vomiting, excessive sweating, systemic illness of any origin, renal impairment, NSAIDs, ACE inhibitors, ARBs, diuretics.

Tell me about lithium and surgery?

Lithium is probably safe in minor surgery but is usually discontinued before major procedures and restarted once electrolytes normalize. The following points should be considered if you will take lithium during the period. Lithium prolongs the action of muscle relaxant, electrolyte imbalance can precipitate lithium toxicity, dehydration can too. increased, increased arrhythmia

What is your dose determined by?

Blood levels.

What is the therapeutic range of lithium?

0.4 to 1 mmol/l

What kind of damage does lithium cause to the thyroid?

It can cause both hyper and hypothyroidism.

What is lithium's lag phase?

5–7 days

What are the neurochemical effects of lithium?

It enhances serotonergic activity, reduces cholinergic activity, and inhibits PI and cAMP.

How is lithium transported across the cell membrane?

It is actively transported across membranes using a voltage-sensitive sodium channel and sodium-potassium ATPase.

Tell me about lithium and signal transduction?

It increases inositol monophosphate. It depletes free inositol. Adrenergic, cholinergic, serotonergic, and dopaminergic receptors are coupled to Pi turnover in the CNS. There is possibly a compensatory stabilization of biogenic amine imbalance. cAMP accumulation is inhibited. All of this is mediated by G proteins. Chronically, it may have effects through protein kinase C and expression of neuromodulators and components of secondary messenger systems.

Tell me about lithium's mechanism of action?

It affects serotonin precursor uptake, synthesis, release, storage, catabolism, receptors, and receptor effector interaction primarily presynaptically. It increases DA turnover, decreases DA formation, decreases striatal DA activity. Facilitates the release of NA through presynaptic autoreceptor. Stimulates Ach synthesis and release.

What percentage of people relapse when on lithium? What percentage relapse on a placebo?

34% relapse on lithium while 81% relapse on placebo.

What percentage relapse and after abrupt termination of lithium?

50% relapse within 5 months.

What can reduce the risk of relapse when you stop the lithium?

Tapering slowly

What percentage of bipolar patients will show an inadequate response to lithium alone and will require the addition of ADT or anticonvulsant?

50%

What patterns of bipolar show reduced the efficacy of lithium?

Rapid cyclers or mixed states. Personality disorders and substance abuse are also associated with poorer response.

Is MDI better or DMI better in lithium treatment?

MDI pattern which is preceding depression responds better to lithium while DMI which is when you get severe episodes of depression don’t respond as well.

How long does lithium take to work in bipolar depression?

3–4 weeks
