Consultant Old Age Psychiatrist

Neuropsychiatry

Difficult to define

Is it the neurology of psychiatry?

Is it the psychiatry of neurology?

Is it something else?
+
Good and Bad
+
Who do you believe?
Kraepelin
Freud

Academic observation

Far more charismatic

Believe that illnesses had a
biological substrate

Better writer

Psychoanalysis

Descendants dominated USA
psychiatry

In 2012 what is his relevance?



Psychopathology
Worked with Alzheimer and
Erb
Dominates ICD-10 and DSM 4
+
Sigmund

Prodigious intellect, a genius

Fluent in seven languages

Reading Shakespeare in English at 7 years of age

Huge personal charm and charisma

Inspirational leader, look at his followers

Provided great insights or alternatively untestable
hypotheses. What are the alternatives to his view about
underlying psychological processes?
+
Why does this matter?

Defines psychiatry

Also and more interestingly it allows psychiatrists to some
extent define themselves

Neuropsychiatrists tend to be neo Kraepelin but the paradox
is that neurologists want them to be Freudian

Very few of us are truly a “tabula rasa”
+
Psychiatry of neurology

Stroke

Brain injury

Epilepsy

White matter disorders

Dementia

Movement disorders

Metabolic disorders etc

Lesion based, pathology based approach
+
This is the central organ
Brain as driver of mind
+
Neurology of psychiatry

Schizophrenia

Mood disorders

Neurodevelopmental hypothesis

Subtle alterations in brain
+ Functional imaging in
schizophrenia
Neuropathological but more subtle
+
What about the neurologists?
+ One of Charcot’s hysterical
patients
These patients are still around.
+
Pathology versus non pathology

Both neurology of psychiatry
and psychiatry of neurology
believe in the concept of a
neuropathology and adopt a
medical model.

Both are neo Kraepelin.

Psychiatry of hysteria, non
epileptic attack disorder,
medically unexplained
symptoms etc, all have a far
more dynamic and Freudian
influenced model.

Intrinsically part of
neuropsychiatry.

Common question themes

The questions come from a single common data bank.

The same themes have been going around and around for
the last thirty years.

The fundamental for CT1 trainees should in my view be the
first part of the MRCPsych.

Basic clinical neurology and psychopathology will make up
about 35% of those questions.
+
Broad outline

Day one

Epilepsy and psychiatry of epilepsy.

Brief introduction to neuropsychiatry.

MCQs

Clinical neuroanatomy and common neurological questions
for the MRCPsych
+
MCQs 1-6

The following are causes of absent knee jerks and extensor
plantars.
 Motor
neuron disease
 Friedreich’s
 Pernicious
ataxia
anaemia
 Complications
A
of diabetes
neurofibroma of the conus medullaris
 Brown-Sequard
syndrome at L2 level
+
MCQs 7-12

The following are true about the pupillary response

A lesion of the retina may impair the response.

Part of the reflex arc takes place in the pons.

They are consensual

A lesion of the abduces nerve may impair the response.

Degeneration of the ciliary ganglion may produce a tonic
pupil

it is possible to be blind wit a normal pupillary response.
+
MCQs 13-20

In Broca’s aphasia

Receptive speech is unimpaired

The lesion is on the contralateral side of the hand dominance of the patient.

Repetition is intact.

Reading is intact.

word production per minute is 4-6

Secondary to stroke, the artery involved commonly originates from the
vertebrobasilar system.

MCQs 26-30

In syringomyelia with associated Arnold Chiari Malformation
the following may be present

Severe positional headaches.

Sensory loss in a cape distribution

Rotatory nystagmus

Cerebellar type dysarthria

Cognitive impairment
+
Now score them up

To pass probably require a score of 20-30.

Questions are a bit odd and slimey but that’s the way of the
game.

Now lunch and reconvene at 1.30 for 2 hours of clinical
neuroanatomy.
