Psychosis, Delusions and Hallucinations – Psychiatry | Lecturio


[Music] we’re going to talk about psychosis delusions and hallucinations now otherwise known as the symptoms that fall under the spectrum of disorders that are known as psychotic disorders let’s start with psychosis and let’s define it psychosis is a break from reality it involves delusions perceptual disturbances and also disorganized thinking what are delusions well these are fixed false beliefs that cannot be altered by rational arguments and cannot be accounted for by the cultural background of the individual there are several delusions we’re going to go through them one by one and I’m gonna give you some case examples from my own experiences as a psychiatrist so one delusion is paranoid thinking this is an irrational belief that one is being followed tracked or somehow targeted here’s an example a patient thinks the FBI is tracking me and they’re stalking my house another common type of delusion is an idea of reference this is a belief that some event is uniquely related to an individual so consider the patient who says newscasters are directly reporting about me this patient believes when they watch TV that people are actually talking about themselves another delusion is thought broadcasting this is the belief that one’s thoughts can be heard audibly by other people so a patient may say I can hear everything you think without you even saying a word another delusion is a deluge or delusion of grandeur this is the belief that one has special powers beyond those of a normal person so consider the person who says I am the smartest person alive I should be president in king of the world that would be a delusion of grandeur delusions of guilt are also common it’s the false belief that one is guilty or responsible for something so consider a patient who says I am solely responsible for my aunt’s failing health when in fact we know it has nothing to do with that patient persecutory delusions are also quite common this is the belief that one is being followed or harassed by gangs or other people so patient may say my classmates are all ganging up on me because I have different opinions and therefore they want to hurt me [Music] erato manic delusions are the belief that a famous movie star or someone with a higher stature is in love with that individual patient may say I am convinced that some famous person loves me and somatic delusions are the belief that the body is somehow diseased so consider the case example of a patient saying my scalp itches and therefore I must have incurable head lice when in fact there’s no obvious explanation for their scalp itching and the doctor has ruled out that they have lice now let’s consider hallucinations another type of a psychotic symptom what exactly are hallucinations these are perceived senses that are not based in reality it’s different from an illusion which is a misinterpretation of an existing sensory stimuli so consider this you’re driving along in your car on a hot day and you perceive a body of water in front of you that would be an illusion it’s not really there but external reality is giving you the impression that it might be there hallucinations are different there are actually a lot of different types of hallucinations so let’s start with auditory hallucinations in other words hearing voices auditory hallucinations are most commonly seen in patients with schizophrenia and there are a lot of different types of auditory hallucinations and it’s really important that with your patient you not only find out if they’re hearing voices but you dig deeper and ask more about them so there could be a command a voice that they’re hearing this is extremely important because that voice might be telling the patient to hurt themselves or others something that you need to screen for they may be hearing a running commentary this is important because running commentary voices are very distressing to individuals so this means that a person is hearing something basically recounting their every move motion and thought it can be very distressing and upsetting in real-time for a patient and then a person may hear one or maybe several voices talking at one time the person who’s hearing several voices at once again is going to be more likely to be disturbed and distressed and they may have a more severe form of a psychotic disorder visual hallucinations otherwise known as seeing things can also occur visual hallucinations are often seen in an illness called Lewy body dementia and also in drug intoxication something very important to keep in mind when you’re making your differential diagnosis of the patient presenting with a visual hallucination olfactory hallucinations are when people smell things can you think of a disorder which often presents as an individual telling you that they smell something funny maybe something burning well well factory hallucinations are often seen in seizure disorder or they’re otherwise known as an aura during epilepsy something very important to keep in mind and tactile hallucinations are when an individual feels something and when you have a patient complaining of this you really want to keep in mind that this could be secondary to drug abuse or alcohol withdrawal that summarizes some of these psychotic symptoms that you may be presented with things like delusions hallucinations it’s important to keep in mind the different types of these disorders and always remember to dig a little bit deeper to get more of a story from your patient behind what they’re actually experiencing [Music] you

    I don’t know, Persecutory delusions? I believe the Bible is the word of God YHWH. A large percentage of my coworkers worship Lucifer, (check out my YouTube video “Repairing the wall” in which they craved a inverted pentagram, next to my desk.) they have been behaving better, but I feel that they are trying to cruse/hex me. Hahaha they read Harry Potter as kids, and now are occultist. I’m praying for them, and I continue to preach to them.

    There is only one God that created Heaven and Earth. Lucifer, the god of this fallen creation has deceived us all. The Bible is a book on genetic warfare. Repent from sin and trust in Yeshua.
