Cerebral palsy (CP) - causes, symptoms, diagnosis, treatment, pathology

Summary

Cerebral palsy is a non-progressive neurodevelopmental condition characterized by brain damage that leads to loss of muscle control. It can result from various causes, including prenatal factors like exposure to radiation or infection, hypoxia, or postnatal causes such as head trauma. The condition is classified into three types: spastic, ataxic, and dyskinetic, each affecting muscle movement differently. While cerebral palsy is incurable, a multidisciplinary approach involving neurologists, rehabilitation specialists, occupational therapists, and speech therapists can help manage symptoms and improve the patient's quality of life. Treatment may include physical therapy, muscle relaxants, botulinum injections, orthotic braces, and sometimes surgery.

Q & A

What is the primary function of the brain in the human body?

The brain acts as the main frame of the body, controlling all functions, whether we are consciously aware of it or not.

What does the term 'cerebral palsy' refer to?

Cerebral palsy refers to a brain condition that causes paralysis, specifically damage to the brain leading to loss of muscle control.

How is cerebral palsy classified?

Cerebral palsy is classified by the type of muscle movements resulting from the brain injury and how it affects the patient's activities.

What is the significance of cerebral palsy being a neurodevelopmental condition?

As a neurodevelopmental condition, cerebral palsy implies that an incident occurs in an area of the brain during its initial development, which can lead to the area not functioning as it should.

What are some prenatal causes of cerebral palsy?

Prenatal causes of cerebral palsy include exposure to radiation or infection during fetal development and hypoxia, where the developing brain doesn't receive enough oxygen.

Can cerebral palsy occur after birth?

Yes, cerebral palsy can occur postnatally due to causes such as head trauma, infection, or a period of oxygen deprivation.

Why is cerebral palsy considered a nonprogressive condition?

Cerebral palsy is considered nonprogressive because, despite the permanent brain damage or injury, the condition does not worsen over time.

What are the three main types of cerebral palsy?

The three main types of cerebral palsy are spastic cerebral palsy, ataxic cerebral palsy, and dyskinetic cerebral palsy.

How does spastic cerebral palsy affect muscle movement?

Spastic cerebral palsy is characterized by tight or stiff muscles, which can make movements appear jerky and is caused by an upper motor neuron lesion affecting the neurons' ability to receive GABA.

What are the symptoms associated with ataxic cerebral palsy?

Ataxic cerebral palsy is characterized by clumsiness or instability in movements and poor balance, caused by damage to the cerebellum, which assists with coordination and fine muscle movements.

How does dyskinetic cerebral palsy present in patients?

Dyskinetic cerebral palsy involves involuntary movements, characterized by dystonia (random slow and uncontrolled movements) and choreoathetosis (random dance-like movements), due to damage or injury to the basal ganglia.

What is the general approach to treating cerebral palsy?

Treatment for cerebral palsy usually involves a multidisciplinary approach, including neurologists, rehabilitation specialists, occupational therapists, speech therapists, and others, to tailor a unique treatment plan for each patient.

Transcripts

it's pretty well established that your

brain's really important it's like if

your body was a computer your brain's

the main frame it controls everything

whether you're aware of it or not

cerebral paly means brain condition

causing paralysis so essentially

cerebral paly refers to damage to the

brain that causes loss of muscle control

like for example if the cerebellum was

damaged patients might have issues with

fine motor skills like writing or

typing that being said though cerebral

pulsy is a broad umbrella term to

basically cover a wide variety of issues

since ultimately the muscle affected and

severity depends on which part of the

main frame's been affected right

cerebral paly is considered a

neurodevelopmental condition meaning

that something happens to an area of the

brain during its initial development

which is an extremely sensitive period

if that area doesn't develop right then

it can't carry out whatever function

it's supposed to

control but what's this vague something

that can happen though well it's

something because there's a wide variety

of causes the majority of cerebral paly

cases are thought to happen before birth

or prenatally which typically means the

underlying cause is really hard to pin

down exposure to radiation or infection

during fetal development can cause

cerebral palsy hypoxia to the developing

fetus has been linked as well in this

case the developing brain doesn't get

enough oxygen potentially from problems

like the placenta not being able to

supply oxygen and

nutrients cerebral palsy doesn't have to

happen prenatally though and some

postnatal causes are things like head

trauma or again an infection or a period

of oxygen

deprivation although most cases are

likely due to some trauma or injury a

very small proportion of cases are due

to a genetic mutation

even though the brain damage or injury

or abnormality is permanent one super

important point to remember about

cerebral py is that it doesn't get worse

over time and for that reason it's

considered a nonprogressive

condition cerebral paly is classified by

the type of muscle movements that result

from the brain injury and how that

affects what activities the patient can

perform the first type is called

cerebral palsy which accounts for about

70% of cases and this is characterized

by having really tight or stiff muscles

which can make patients movements seem

jerky this tightness results from Aion

in an upper motor neuron so with Aion

which just means some kind of

abnormality the ability of some of these

neurons to receive Gaba might be

impaired and Gaba is the main inhibitory

neurotransmitter so if nerve impulses

can't be inhibited which is a double

negative then those nerves are basically

OV excited leading to hypertonia which

is an abnormal increase in the muscle

activity basically like if the muscles

were constantly

Contracting this is why some people with

cerebral paly have a scissor

gate think about how hard it' be to walk

when your adductor muscles were always

partly contracted which causes your

knees and thighs to constantly touch

similarly sometimes patients have a toe

walk because their calf muscles are

always contracted which pulls the

Achilles tendon up and causes someone to

go up on their

toes a second type of cerebral palsy is

aoid or dis kinetic cerebral paly and

this one involves damage or injury to

the basil ganglia the basil ganglia is

this structure here which essentially

helps us to initiate and prevent certain

movements if the basil ganglia becomes

damaged patients can lose the ability to

prevent movements and therefore they can

have involuntary movements meaning out

of their control

so dis kinetic cerebral paly is

characterized by distonia and or Chia

distonia is random slow and uncontrolled

movements in the limbs and trunk Coria

is random dance-like movements since the

small uncontrolled movements seem to

move from muscle to

muscle finally there's axic cerebral

paly taxis refers to an order or

Arrangement so axic essentially means

without order which is in reference to

patients with this type being shaky or

uncoordinated and this is caused by

damage to the cerebellum which helps

with coordination and fine or precise

muscle movements these patients often

have clumsy or unstable movements and

poor balance when doing things like

walking or picking something up although

different from Patient to Patient many

patients with muscle control issues have

other symptoms as well patients often

experience pain from tighten muscles or

abnormal posture and stiff joints also

abnormal movements might make it

difficult to sleep at night and patients

can develop Sleep Disorders eating can

become difficult as well which can range

from the preparation of food to the

action of chewing and swallowing food

other brain related issues are also

Associated like difficulties with

speaking and communication vision

problems and learning

disabilities diagnosis of cerebral paly

is typically done clinically however in

some cases additional lab work can be

done to rule out other conditions that

present similarly such as thyroid

disorders or inherited metabolic

conditions Imaging tests like a brain or

spine MRI or CT scan can also support

the diagnosis of cerebral paly or rule

out other central nervous system

lesions since cerebral palsy involves a

permanent abnormality to the brain

structure it's not curable but that

doesn't mean it's not treatable

treatment for cerebral paly usually

involves a multidisciplinary approach

pulling from a number of clinical iCal

Specialties like neurologists

Rehabilitation Specialists occupational

therapists speech therapists and others

hopefully to find a unique approach for

each patient ultimately improving their

quality of

life Physical Therapy can be used to

build strength and improve walking

ability along with stretching to reduce

contracture which is a permanent

shortening of muscle tissue from being

hypertonic or contracted for so

long sometimes muscle relaxants are

given or botulinum is injected into

certain muscles to relax them which can

both help reduce pain associated with

hyp tonis and also help fit patients

with specific orthotic

braces sometimes surgery might also be

performed to help with a variety of

issues like loosening tight muscles

straightening out bones that have been

subject to abnormal muscle forces over

time and cutting certain nerves to

reduce their Associated movements or

spasms all right it's a quick recap

cerebral paly is when Central Cal

nervous system structures like the brain

or cerebellum are damaged and this

affects motor function causing palsy

even though the damage is permanent the

condition doesn't get worse over time so

it's considered a non-progressive

disorder there are three types of
