Introduction to the Central Nervous System pt.2

💊 Tricyclic Antidepressants (TCAs)

What do they do?

😔 Depression = Low NE + Low 5HT

Your brain normally "takes back" (reuptakes) these neurotransmitters after they send a message.

TCAs block the reuptake .

This means:

🧠 More NE stays in the brain

🧠 More 5HT stays in the brain

↓

😊 Mood improves

Imagine NE and 5HT are workers.

Normally they leave work too soon.

🚶‍♂🚶‍♀

TCAs lock the exit door.

🚪🔒

Now more workers stay and help.

📌 TCA = Keeps NE and 5HT around longer.

⏳How Long Does It Take To Work?

Not right away!

It usually takes:

2–4 weeks before the full effect is felt.
"TCAs Take Time."

If you stop the drug

The effects may remain for about 2 weeks after stopping.

therapeutic effect remains about 2 weeks after D/C of the drug,

Tricyclic Antidepressants (TCAs)

😴 Common Side Effects

TCAs can make the body SLOW and DRY

😴 Sedation/Drowsiness

It makes you sleepy.

👄 Dry Mouth

Less saliva.. Mouth feels dry.

🚽 Constipation

Harder to poop.

💧 Urinary Retention

Harder to pee.

Bladder doesn't empty well.

💊 MAO Inhibitors (MAOIs) Step 1: What is MAO?

MAO = Monoamine Oxidase

It's an enzyme in your body.

Think of MAO as a:

🧹 Cleanup Crew

Its job is to clean up extra:

• NE (Norepinephrine) ⚡

• 5HT (Serotonin) 😊

after they're used.

Step 2: What do MAOIs do?

MAOI = MAO Inhibitor

"Inhibitor" means stop .

So MAOIs stop the cleanup crew.

Normally:

MAO 🧹 → cleans up NE and 5HT

With MAOI:

MAO is blocked ❌

Result:

⬆ More NE

⬆ More 5HT

↓

😊 Depression symptoms improve

MAO = Maid

🧹 MAO cleans up neurotransmitters.

MAOI = Stop the Maid ❌🧹

Now more NE and 5HT stay around.

⏳ How Long Does It Take?

Not immediate.

Usually: 2–4 weeks for full effect.
"MAOIs Move Along Slowly."

MAO Inhibitors (MAOIs)

🚨 MOST IMPORTANT THING

Avoid Tyramine Foods

What is Tyramine?

A substance found in certain foods.

If someone taking a MAOI eats lots of tyramine:

⬆ Huge release of NE

↓

⬆ Blood pressure shoots up

↓

🚨 Hypertensive Crisis

(very dangerous high blood pressure)

↓

Can lead to stroke.

MAOI + Tyramine = Trouble

🚨 High Blood Pressure

Foods to Avoid

You do NOT need to memorize every food.

Think:

OLD, AGED, FERMENTED FOODS

Examples:

🍷 Wine

🍺 Beer

🧀 Aged cheese

🥫 I am a sauce

🍌 Overripe bananas

🥑 Overripe avocados

🍇 Raisins

🥩 Liver

🌭 Sausages

"If it's aged, fermented, or overripe—avoid it with MAOIs."

MAO Inhibitors (MAOIs)

Other Side Effects

These are very similar to TCAs.

Think:

Dry

👄 Dry mouth

🚽 Constipation

💧 Urinary retention

👀 Blurred vision

Dizzy

⬇ Hypotension

(Low blood pressure)

Weight/Sexual

⚖ Weight gain

❤ Sexual dysfunction

Nervous System

✋ Tremors

😣 Restlessness

Liver Warning

🟡 Yellow skin or eyes=Jaundice

Report it immediately.

MAOIs interact with MANY medications.

Always check with a doctor or pharmacist before taking new medications.

💊 SSRI = Serotonin Saver

Remember:

😔 Depression = Low 5HT (Serotonin)

The brain normally takes serotonin back after it sends a message.

This is called reuptake .

What do SSRIs do? MOA (Mechanism of Action)

SSRIs block serotonin reuptake .

Think:

Normally:

5HT 😊 → sends message → gets taken back

SSRI:

5HT 😊 → sends message → stays around longer

Result:

⬆ More serotonin in the brain

😊 Better mood

📌 Memory Trick:
SSRI = Save Serotonin

Imagine serotonin is a teacher.

👩‍🏫 Serotonin helps students (brain cells).

Normally the teacher leaves too quickly.

SSRI says:

❌ "Stay longer."

Now the teacher helps more students.

😊 Mood improves.

💊 Miscellaneous Antidepressants

What does "Miscellaneous" mean?

📌 "Doesn't fit into the other groups."

These antidepressants work in different ways.

Some affect:

😊 5HT (Serotonin)

⚡ NE (Norepinephrine)

🎯 DA (Dopamine)

Some affect one, some affect several.

Miscellaneous = Mixed Methods

Think:

🧰 Toolbox

Every tool works differently.

That's why the notes say:

"MOAs vary." (MOA = Mechanism of Action)

💊 Miscellaneous Antidepressants

Side Effects

Because these drugs work differently:

📌 Side effects can be different depending on the specific drug.

But common ones include:

Symptom Relief

This is explaining when antidepressants start helping.

A lot of people think:

💊 Take antidepressant today

😊 Feel better tomorrow

But that's not how it works.

🧠 Antidepressants Work Slowly

📌 Memory Phrase:
"Sleep first, Think second, Mood last."

Week 1 What improves first?

😴 Sleep improves

The person may:

• Sleep better

• Eat more normally

Week 1 = Sleep & Eat

Weeks 1–3 What improves next?

🧠 Concentration improves

🤔 Thinking becomes clearer

🚿 Self-care improves

❤ Sexual desire may increase

The person may:

• Focus better

• Take better care of themselves

• Have more energy

Weeks 1–3 = Think & Take Care

Weeks 4–6 What improves last?

😊 Mood improves

🌤 Less hopelessness

😴 Week 1

🧠 Weeks 1–3

😊 Weeks 4–6

💊 Safety Measures (Super Easy) 1-4

1. Don't Stop Suddenly

❌ Don't just stop taking antidepressants on your own.

Why?

Your brain gets used to the medication.

Stopping suddenly can cause problems and symptoms to return.

✅Always follow your doctor's instructions.
"Don't Stop Cold Turkey."

2. Stop Only With a Doctor's Help

Sometimes the dose needs to be lowered slowly.

This is called tapering.

Think:

Bad:100 → 0 ❌

Better:100 → 75 → 50 → 25 → 0 ✅

"Slowly go, don't suddenly stop."

3. Medication Alone Isn't Enough

Antidepressants help, but people often need:

❤ Family support

🤝 Friends

🗣 Counseling/Therapy

along with medication.

Think of depression treatment like a team:

💊 Medication

🗣 Counseling

❤ Support System

=

Better results
"Pills + People = Better Healing."

4. Be Careful Mixing Antidepressants

Some antidepressants increase serotonin.

If too many serotonin-raising drugs are taken together (for example, an MAOI and an SSRI), serotonin can become too high.

This can cause:🚨 Serotonin Syndrome

Safety Measures

🌟 Ultimate Memory Phrase

Normal serotonin:

😊 Good

Too much serotonin:

🚨 Dangerous

Signs of Serotonin Syndrome

Think:

HOT + SWEATY + SHAKY

🌡 Fever

🥵 Sweating

✋ Tremors

❤ Fast heart rate

🤯 Confusion

😣 Agitation
"Too much serotonin = Hot, Sweaty, Shaky."

Safety Rule	Easy Meaning
Don't stop suddenly	Follow doctor's instructions
Taper slowly	Reduce dose little by little
Need support	Medication + counseling + family/friends
Mixing antidepressants	Can raise serotonin too much
Serotonin Syndrome	Dangerous serotonin overload

"Don't stop suddenly, get support, and don't mix serotonin drugs without medical guidance."

Or even shorter:

💊 Take safely

❤ Get support

🚨Watch for serotonin syndrome

Mania

This is actually the opposite of depression.

Remember:

😔 Depression = Low mood, low energy

😃 Mania = Extremely high mood, extremely high energy

🧠 Mania

Mania is a mental state where a person becomes:

⚡ Very energetic

😃 Extremely happy/excited

🚀 Overactive

🗣 Very talkative

What's happening in the brain?

According to your notes:

⬆ NE (Norepinephrine)

⬆ 5HT (Serotonin)

Too much activity can lead to mania.
"High chemicals = High mood."

Mania

Symptoms of Mania

⚡ Hyperactivity

Lots of energy.

Always moving.

Can't sit still.

Example:

Everyone is relaxing, but the person is constantly doing something.

😃 Elated Mood

Feeling extremely happy or excited.

Not just normal happiness.

Think:

🚀 "I'm on top of the world!"

🤔 Unrealistic Thoughts and Ideas

The person may believe things that are unrealistic.

Examples:

• "I can do anything."

• "I don't need sleep."

• "I'm going to become a millionaire tomorrow."

🗣 Talkative

He talks much more than usual.

I can talk very fast.

May jump from topic to topic.

🎉 Extremely Spontaneous

Acts without thinking things through.

Examples:

💸 Spending lots of money suddenly

✈ Making big plans on impulse

🎁 Buying things they can't afford

Mania

🌟 Ultimate Memory Phrase

Depression	Mania
😔 Sad	😃 Extremely happy
😴 Low energy	⚡ High energy

🗣 Very talkative

🤔 Unrealistic ideas

🎉 Impulsive/spontaneous behavior

🌟 Ultimate Memory Phrase

"Depression is too low, Mania is too high."

😔 Depression = Low mood, low energy

🚀 Mania = High mood, high energy, high activity

🧠 Bipolar Mood Disorder What is it?

A person goes back and forth between:

😔 Depression (low mood)

and

🚀 Mania (high mood)

📌 "Bi" = Two Bipolar = Two moods

1. 😔 Depression

2. 🚀 Mania

What does "alternating cycles" mean?

It means the moods change over time.

Example:

😔 Depression

↓

😊 Normal

↓

🚀 Mania

↓

😊 Normal

↓

😔 Depression

The person doesn't stay in one mood forever.

Their mood can cycle between highs and lows.

What are "Mood Episodes"?

A mood episode is a period of time when someone is:

😔 Depressed

OR

🚀 Manic

Think: 📌 Episode = Mood Phase

Old Name

Bipolar disorder used to be called:

Manic-Depressive Disorder

Because it involves:

🚀 Mania

and

😔 Depression

Bipolar Mood Disorder

What is polypharmacy?

Poly = Many Pharmacy = Medications

SW:

📌 Polypharmacy = Taking more than one medication

Many people with bipolar disorder need multiple medications to help control both mania and depression.

Subcategories

Not everyone has bipolar disorder in the same way.

Doctors classify it based on:

• How long do symptoms last? ⏳

• How many mood episodes occur 🔄

• The pattern of mood changes 📈📉

Don't worry about memorizing the subtypes right now.

Just know:

📌 Different people have different patterns of highs and lows.

• subcategories classified by length of symptoms and number, length, and pattern of mood episodes

Bipolar Mood Disorder

Easy Story

Imagine a mood roller coaster 🎢

Sometimes:

😔 Very low → Depression

Then later:

🚀 Very high → Mania

The roller coaster goes up and down.

That is bipolar disorder.

Term	Easy Meaning
Bipolar Disorder	Alternating depression and mania
Bi	Two
Depression	Low mood
Mania	High mood
Mood Episode	A period of depression or mania
Manic-Depressive Disorder	Old name for bipolar disorder
Polypharmacy	More than one medication

"Bipolar = Two Opposite Moods."

😔 Depression = Down

🚀 Mania = Up

🎢 Bipolar Disorder = Mood Roller Coaster 🎢

That's the main idea your instructor wants you to understand. 🧠✨

Bipolar and Mania Treatment

💊 Antimania Drug (Lithium)

Why do we use it?

🚀 Mania = Brain is TOO active

The person may be:

⚡ Hyperactive

🗣 Talking nonstop

😃 Extremely excited

🤔 Having unrealistic ideas

Lithium helps slow the brain down .

📌 Memory Trick:
"Lithium Lowers Mania."

🧠 How Does It Work? (MOA)

Don't worry about the complicated wording.

The main idea:

Lithium calms overactive nerve cells.

Item:

⬇ Decreases nerve excitability

⬇ Decreases release of NE and other neurotransmitters

⬆ Increases reuptake of neurotransmitters

Result:

🧠 Less neurotransmitter activity

↓

🚀 Less mania

Super Easy Memory

Mania = Too Much GO

antimania/Lithium = Slow Down and Chill 🛑

Bipolar and Mania Treatment

⏳ How Long Until It Works?

Not immediately.

Usually:1–2 weeks

before you see improvement.

📌 Memory:
"Lithium Takes a Little Time."

🧂 Sodium Is Important

Lithium and sodium are related.

The patient should have:

✅ Normal/adequate sodium intake

Why?

It helps the body get rid of lithium properly.

📌 Easy Memory:
"Lithium Likes Salt Balance."

Common Side Effects

💧 Thirst

Feeling thirsty more often.

---

✋ Tremors

Shaky hands.

---

🤢 Nausea

Upset stomach.

---

Easy Memory

"Lithium = Thirsty, Shaky, Queasy."

💧 Thirsty✋ Shaky🤢 Queasy

Bipolar and Mania Treatment

🩸 Drug Levels Must Be Checked

Antimania/Lithium can become toxic if levels get too high.

That's why doctors do:

🩸 Blood tests

Regularly.

📌 Memory:
"Check Lithium Levels."

Thyroid Effects

Lithium can affect the thyroid gland.

The thyroid helps control metabolism and energy.

Doctors may monitor thyroid function.

🚨 Overdose Symptoms

If lithium levels get too high:

🤮 Vomiting

💩 Diarrhea

🔔 Ringing in ears (tinnitus)

⬇ Low blood pressure

😵 Loss of balance/equilibrium

Easy Memory

"Too Much Antimania/Lithium = Stomach Problems + Balance Problems."

☠ Toxic Levels (Very Serious)

Very high lithium levels can cause:

🩺 Nephritis = Kidney damage/inflammation

❤ Arrhythmias = Abnormal heartbeat

🧠How is Bipolar Disorder Treated?

Because bipolar disorder has:

😔 Depression (low mood)

And

🚀 Mania (high mood)

Doctors often need more than one treatment .

💊 Types of Medications

1. Antimanic Drugs

These help control:

🚀 Mania

They calm the brain down.

Example:💊 Lithium

📌 Memory:
Antimanic = Anti-Mania

2. Atypical Antipsychotics

These help with:

🚀 Mania

🤔 Unrealistic thoughts

😣 Severe mood symptoms

Think:📌 "Helps calm extreme symptoms."

3. Antidepressants

These help with:

😔 Depression

Examples:

• SSRIs

• SNRIs

But in bipolar disorder, doctors are careful because some antidepressants can sometimes trigger mania.

4. Anticonvulsants (AEDs)

Originally used for seizures.

Some also help:

⚖ Stabilize mood
"Mood Stabilizers."

5. Anti-Anxiety Medications

Help reduce:

😰 Anxiety😟 Nervousness😬 Agitation

Bipolar Mood Disorder Therapy

What is polypharmacy?

Poly = Many Pharmacy = Medications

📌 Polypharmacy = More than one medication

A person with bipolar disorder may need:

💊 Lithium

PLUS

💊 Antidepressant

PLUS

💊 Anti-anxiety medication

Why?

Because one medication may not control all symptoms.

Finding the Right Combination Takes Time

Not every medication works the same for every person.

Doctors may need to:

✅ Try one medication

✅ Adjust the dose

✅ Add another medication

until they find the best combination.

📌 Memory:
"Right drug combo takes time."

Support System and Counseling

Medication is important.

But people also benefit from:

❤ Family support

🤝 Friends

🗣 Counseling/Therapy

💊 Medication

➕

🗣 Counseling
