Q & A
What are hallucinations in the context of schizophrenia?
-Hallucinations in schizophrenia are disturbances of perception where a person experiences false sensory experiences, believing they are experiencing something through one of the five senses when they are not.
How do hallucinations typically affect individuals with schizophrenia?
-Hallucinations are typically very distressing for individuals with schizophrenia because they feel as real as actual experiences, regardless of whether they involve hearing, seeing, or feeling something that is not really there.
Which sense is most commonly affected by hallucinations in schizophrenia?
-The auditory sense is the most common sensory modality affected by hallucinations in schizophrenia, with the most common type being the experience of hearing voices.
What is the typical nature of the voices heard in auditory hallucinations?
-The voices heard in auditory hallucinations are typically derogatory and negative towards the person experiencing them, often saying mean things like 'he's worthless' or 'he's useless.'
How can one differentiate between thoughts and auditory hallucinations?
-The key difference between thoughts and auditory hallucinations is whether the individual feels the words are coming from inside or outside their own mind. Thoughts are internal, while auditory hallucinations feel external.
Can hallucinations occur in senses other than hearing?
-Yes, hallucinations can occur in any of the other senses, including visual, olfactory, gustatory, and tactile hallucinations.
What is the significance of considering organic causes for hallucinations?
-It is important to consider organic causes for hallucinations because they can be a product of organic brain disease. An organic cause should be ruled out early on, even if other aspects of the person's presentation are consistent with a psychotic illness.
What is an example of an olfactory hallucination mentioned in the script?
-An example of an olfactory hallucination is a 27-year-old woman experiencing the smell of burning human flesh, which was not actually present.
How are gustatory hallucinations experienced?
-Gustatory hallucinations involve the sense of taste, where a person experiences tasting something that they are not actually tasting, such as food tasting rotten to them while others eating the same food find it fine.
What is a common example of a tactile hallucination?
-A common tactile hallucination is the sensation of something crawling on or under the skin, like maggots or cockroaches, when no such physical contact is occurring.
Why is it crucial to exclude organic causes before attributing hallucinations to schizophrenia?
-It is crucial to exclude organic causes before attributing hallucinations to schizophrenia to ensure accurate diagnosis and appropriate treatment. Organic causes may require different interventions compared to those for schizophrenia.
Outlines
đ Hallucinations in Schizophrenia
This paragraph discusses hallucinations as a symptom of schizophrenia, which are false sensory experiences that can be very distressing. The most common type of hallucination for individuals with schizophrenia is auditory, where they hear voices that are typically derogatory and negative. The paragraph also distinguishes between these hallucinations and a person's internal monologue, clarifying that the key difference lies in whether the voices seem to originate from inside or outside the individual's mind. Other forms of hallucinations, such as visual, olfactory, gustatory, and tactile, are also mentioned, with the caveat that an organic cause must be ruled out before attributing them to schizophrenia.

Highlights
Hallucinations in schizophrenia are disturbances of perception, causing false sensory experiences.
Hallucinations can occur through any of the five senses and are typically distressing.
Auditory hallucinations are the most common, often involving derogatory voices.
Negative voices in auditory hallucinations are usually critical, saying things like 'he's worthless'.
Positive auditory hallucinations are rare, with only one benign case mentioned in the transcript.
The distinction between thoughts and auditory hallucinations lies in whether the voice seems internal or external.
Visual hallucinations should prompt consideration of organic brain disease as a potential cause.
Organic causes must be ruled out for any type of hallucination before attributing it to schizophrenia.
Olfactory hallucinations involve the false perception of smells, such as the distressing smell of burning flesh.
Gustatory hallucinations are the false experience of taste, like food tasting rotten to the person.
Tactile hallucinations create a false sense of touch, such as feeling insects crawling on the skin.
It's crucial to differentiate between internal thoughts and external auditory hallucinations for diagnosis.
The need for medical investigations like MRI to exclude organic causes before diagnosing hallucinations as schizophrenia.
Hallucinations can significantly impact the individual's well-being, making it essential to address them in treatment.
The importance of understanding the nature of hallucinations for accurate diagnosis and appropriate treatment.

The variety of sensory experiences that can be affected by hallucinations, highlighting the complexity of the condition.
Transcripts
The next symptom set of schizophrenia is hallucinations, which are disturbances of perception.
When a person experiences hallucinations, they are having a false sensory experience.
They believe that they are experiencing something through one of the five senses when in fact
they are not.
Hallucinations, like delusions, are typically very distressing for the people who experience
them, because the experienceââwhether it involves hearing, seeing or feeling something
that is not really thereââfeels every bit as real as if it was actually happening.
For people with schizophrenia, by far the most common sensory modality in which hallucinations
are experienced is the auditory sense.
Auditory referring to what we hear.
The most common type of auditory hallucination that people with schizophrenia experience
is hearing voices.
Typically, when a person is experiencing auditory hallucinations and hearing voices, the voices
are very derogatory and negative about the person in question.
A person may hear one or more voices, but generally, theyâre saying awful, mean things
to the person â for example, âheâs worthlessâ, "he's useless".
Itâs very unusual for the voices to say anything positive about the person experiencing
them.
In many years of working as a clinical psychologist, Iâve only ever met one person who experienced
voices that were benignââthat said nice things to her.
Sometimes, when a person says they are hearing voices, they are actually talking about their
own thoughts, or internal monologue.
The key difference between thoughts and an auditory hallucination in the form of âa
voiceâ is whether the individual feels that the words being spoken are coming from inside
or outside of their own mind.
Generally speaking, people are able to be quite clear on this issue.
If the words or voices are coming from inside your mind, weâre usually talking about a
thought or self-talk.
Whereas, if the words or voices are coming externally, as though someone else is talking
to you, weâre usually talking about an auditory hallucination.
Although auditory hallucinations are the most common form of hallucinations, these false
sensory experiences can occur in any of the other senses.
Visual hallucinations refer to the experience of seeing something that is not actually there.
Importantly, if a client tells you that they are experiencing visual hallucinations, you
need to keep in mind that visual hallucinations can be a product of organic brain disease.
Actually, this possibility â an organic cause â needs to be kept in mind for any
type of hallucination.
So, the possibility of an organic cause needs to be ruled out very early on.
Even if other aspects of the personâs presentation are consistent with a psychotic illness, we
need to exclude organic causes, by referring the client for an MRI or whatever other investigation
is appropriate.
It is possible for somebody with schizophrenia to experience visual hallucinations, but you
need to exclude organic causes first before attributing it to schizophrenia.
Olfactory hallucinations involve the sense of smell â so this is where someone has
the experience of smelling something that in fact is not there.
One example that stands out for me over the years is a 27-year-old woman who had a very
distressing olfactory hallucination, whereby she would quite frequently experience the
smell of burning human flesh.
Gustatory hallucinations involve the sense of taste.
So, when a person experiences a gustatory hallucination, they have the experience of
tasting something that they are not actually tasting.
A common example is the experience that the food you are eating tastes rotten when it
tastes fine to others who are eating the same food.
Finally, a tactile hallucination refers to a false sensory experience in relation to
the sense of touch.
When a person has a tactile hallucination, there is the sense of physical contact with
a stimulus that is not real.
One of the most common tactile hallucinations is the experience of something crawling on
or under your skin.
For example, maggots or cockroaches.
