Stimulant medications like Adderall and Ritalin are commonly used to treat ADHD and improve focus. These medications work by affecting the activity of brain networks, including the prefrontal cortex. They increase dopamine and norepinephrine levels in the brain, reducing distractions and improving attention. However, excessive dopamine and norepinephrine can lead to euphoria, mania, psychosis, anxiety, and panic attacks. It is crucial to appropriately dose and prescribe these medications for the specific condition. Recreational use of these drugs can lead to addiction and an increased risk of psychosis. The long-term effects of these medications on height, cardiovascular health, and hormone systems are still being studied. It is important to work closely with a psychiatrist to find the right dosage and type of medication for each individual. Drug holidays and non-stimulant medications like Guanfacine are also discussed as alternative options for ADHD treatment.

Attention, Prefrontal Cortex & ADHD
Attention, Prefrontal Cortex & ADHD:
Attention is a complex cognitive process that involves the suppression of noise and the ability to focus on specific things. The prefrontal cortex plays a critical role in orchestrating active neural circuits during attention.
ADHD is not a deficit in prefrontal cortical function, but rather a difficulty in regulating other brain networks.
The default mode network, responsible for internal thoughts and imagination, remains active in individuals with ADHD, leading to distractions and difficulty in staying focused.
Stimulant medications like Adderall and Ritalin can alleviate ADHD symptoms by affecting the activity of brain networks, including the prefrontal cortex.
Understanding the biology of these medications is crucial in making informed decisions about their use.
Stimulants “Sympathomimetics”
Stimulants, such as amphetamines, are commonly used to treat ADHD symptoms. They activate the sympathetic arm of the autonomic nervous system, improving focus and attention. Methamphetamine is the most potent sympathomimetic, but is rarely prescribed due to its negative effects. Adderall and Vyvanse are commonly prescribed alternatives.
Adderall, Dopamine & Norepinephrine
Adderall is a combination of amphetamine salts that affects receptors in the brain and increases blood pressure and heart rate. It primarily increases the activity of dopamine and norepinephrine, important neurotransmitters in the brain.
Key points:
- Adderall contains D-amphetamine and L-amphetamine, with D-amphetamine being more potent and affecting receptors in the brain.
- L-amphetamine primarily increases blood pressure and heart rate.
- Dopamine increases motivation, pursuit, and mood, while norepinephrine enhances attention and focus.
- Dopamine and norepinephrine work together to achieve increased motivation, focus, and alertness.
- Drugs used to treat ADHD enhance these qualities at specific locations in the brain.
Sympathomimetics, Dopamine & Norepinephrine
Sympathomimetics like Adderall increase dopamine and norepinephrine levels in the brain by inhibiting reuptake and disrupting vesicle transporters. This leads to increased neurotransmitter levels in the synapse and improved focus and attention spans. Key points include:
- Adderall inhibits the transporters that reuptake dopamine and norepinephrine, allowing more neurotransmitters to bind to receptors and increase their levels in the synapse.
- Adderall disrupts vesicle monoamine transporters, leading to a buildup of dopamine and norepinephrine in the presynaptic terminal and increased release.
- Adderall affects the entire network of proteins involved in dopamine and norepinephrine transmission.
- Sympathomimetics like Adderall and Modafinil are commonly used for ADHD treatment due to their ability to increase dopamine levels and improve focus.
Vyvanse is Timed-Release D-Amp
Vyvanse, a time-release form of d-amphetamine, is designed to prevent abuse potential. It provides a slow and long-lasting increase in dopamine and norepinephrine, lasting 12 to 18 hours. Finding the right dosage and type of sympathomimetic is a trial-and-error process. Different options for sympathomimetics for ADHD exist.
Ritalin, Concerta
Ritalin, also known as Concerta, is a commonly prescribed drug for the treatment of ADHD. It increases dopamine and norepinephrine levels at synapses, but to a lesser extent than drugs like Adderall and Vyvanse. Ritalin primarily affects dopamine transmission, while Adderall and Vyvanse affect both dopamine and norepinephrine.
Dopamine & “Noise Reduction”; Norepinephrine & “Signal Amplification”
Dopamine and norepinephrine are crucial for executive function and attention in the prefrontal cortex. Dopamine acts as "noise reduction," quieting distractions and allowing for better focus. Norepinephrine enhances signal amplification, increasing communication between neurons. Drugs like Adderall and Ritalin increase both dopamine and norepinephrine, resulting in reduced noise and amplified signals, improving attention and focus.
ADHD: Focus, Hyperactivity & Impulsivity; Drug Selection & Dose
ADHD is characterized by challenges in focusing on various activities required for normal life progression. It is not simply an inability to focus, but rather an extreme variation in the ability to focus. The effectiveness of stimulant medications, such as Adderall and Modafinil, in treating ADHD can vary depending on factors such as dosage, individual sensitivity, and developmental stage. These medications work by increasing dopamine and norepinephrine levels in the brain, reducing distractions and improving focus. However, excessive dopamine and norepinephrine can lead to euphoria, mania, psychosis, anxiety, and panic attacks. It is crucial to appropriately dose and prescribe these medications for the specific condition. Not all individuals with ADHD experience impulsivity and hyperactivity, as some may only struggle with focus. Finding the ideal drug and dosage for each individual's specific pattern of ADHD requires consulting a qualified psychiatrist.
How do Stimulants ‘Calm’ ADHD?
Stimulants like Adderall and Modafinil treat ADHD by increasing dopamine and norepinephrine levels in the brain. However, ADHD is characterized by hyperconnectivity between brain networks. Stimulants tune the neurotransmitter levels in specific networks, activating the prefrontal cortex and improving focus and attention.
Key points:
- ADHD is not simply a deficiency in dopamine and norepinephrine.
- Stimulants adjust neural circuits in the brain.
- They help activate and sequence attention networks.
- Regulating neurotransmitter levels improves focus and attention in individuals with ADHD.
Neuroplasticity & Neuromodulators
Neuroplasticity refers to the brain's ability to change and adapt in response to experience. This process is induced by strongly activating certain brain networks, leading to elevated release of neuromodulators such as dopamine and norepinephrine. These neuromodulators, along with others like serotonin and acetylcholine, play different roles in the brain. When dopamine and norepinephrine levels increase significantly, they promote neuroplasticity at specific synapses. It is important to note that neuromodulators modulate the activity of neurotransmitters between neurons.
Kids, ADHD Diagnosis & Treatment; Predispose Addiction?
Prescribing stimulant medications to children with ADHD promotes neuroplasticity in the brain networks responsible for focus, leading to improved focus efficiency even after stopping the medication. Research shows that appropriately treated children with ADHD perform better in school and have improved overall outcomes. Concerns about addiction or illicit drug abuse later in life have been addressed by studies, indicating that early treatment with these medications does not predispose individuals to addiction.
Children with untreated ADHD have a higher tendency towards illicit drug use and addiction in adulthood. However, children with ADHD who take prescription drugs during development do not show a craving for these drugs later in life. Early treatment with these drugs normalizes circuits over time by increasing dopamine transmission in the forebrain. Accurate diagnosis and a comprehensive approach that includes both pharmacologic and behavioral treatments are important for effective ADHD management in children.
ADHD Medications: Individuality, Doses, Tapering & Long-Term Use
ADHD medications are designed to improve neural circuits related to focus, and continued use may be necessary for some individuals. It is recommended to discuss tapering off with a psychiatrist to assess if continued use is necessary. Abruptly stopping these medications can lead to withdrawal symptoms.
Key points:
- Close communication with a psychiatrist is important when going off or reducing dosage of ADHD medications.
- Reductions in dosage over time are often optimal for patients.
- Dosage ranges for different ADHD medications can vary and translating between dosages of different drugs is challenging.
- The dosage of ADHD medications can vary greatly among individuals, and there is no simple test to predict an individual's response.
- The safest and most effective approach is to start with the lowest possible effective dose and increase as needed.
Medication & Long-Term Effects: Height, Cardiovascular Risk, Alcohol
The use of drugs like Adderall, Ritalin, and Vivance for ADHD treatment does not appear to negatively impact height or overall development. Children with ADHD who are treated with these medications may have slightly higher body mass indexes compared to their peers. However, long-term use of these medications carries some cardiovascular risk, as it can lead to higher blood pressure, heart rate, and other stress-related symptoms. It is important to consider the potential long-term effects on cardiovascular health when using these medications for ADHD treatment.
- ADHD medications do not stunt growth or impair maturation
- Children treated with these medications may have slightly higher body mass indexes
- Long-term use of these medications carries cardiovascular risk
- Increased sympathetic activity can lead to higher blood pressure, heart rate, and other stress-related symptoms
- Find the minimal effective dosage and take steps to improve cardiovascular health
- Avoid alcohol consumption while taking ADHD medications
- Combining alcohol with ADHD medications is not recommended
- Combining these medications with alcohol or benzodiazepines can be detrimental to the brain and body
- These medications can impact the hormone systems of the body.
Cortisol & Hormones
Stimulant drugs used for ADHD can impact cortisol levels, a stress hormone with important roles in the body. Timing of medication intake is crucial, as cortisol release should be higher in the morning and lower at night. Different ADHD drugs have varying durations of action, with Ritalin being short-lived, Adderall having an intermediate duration, and Vyvanse being long-lasting. Short-acting drugs may be preferable for maintaining sleep, while long-acting drugs can inhibit sleep. Adderall may be suitable for individuals who need medication throughout the day but still want to fall asleep at night. However, there is limited research on the long-term effects of these drugs on the endocrine system.
Key points:
- Stimulant drugs for ADHD can increase cortisol levels.
- Timing of medication intake is important for cortisol regulation.
- Different ADHD drugs have varying durations of action.
- Short-acting drugs may be better for sleep maintenance.
- Long-acting drugs can inhibit sleep.
- Adderall may be suitable for daytime use and sleep at night.
- Limited research on long-term effects of ADHD drugs on the endocrine system.
Psychosis & Addiction; Methamphetamine
The most profound aspect of the topic is the relationship between psychosis and addiction in individuals using methamphetamine.
Key points:
- Individuals with ADHD who are appropriately treated with medication have a lower risk of addiction.
- Withdrawal effects can occur when someone stops or tapers off ADHD medication.
- Amphetamines, including ADHD medication, can induce psychosis.
- Predisposing factors for psychosis include having a first-degree relative with psychosis.
- Taking sympathomimetic drugs like amphetamine and methylphenidate can increase the likelihood of psychotic episodes, especially for individuals with a predisposition to schizophrenia or bipolar disorder.
- Methamphetamine is a highly dangerous drug that can induce psychosis even in individuals without a predisposition.
- Prescription methamphetamine is rarely used due to its narrow clinical applications.
- ADHD drugs containing amphetamine have a higher likelihood of inducing psychosis in individuals with a predisposition.
- Methylphenidate carries a lower potential for inducing psychosis compared to amphetamine-based drugs.
- Vyvanse, a long-release form of amphetamine, has some protective factors against psychosis and abuse potential.
- Methamphetamine releases five times more dopamine than other drugs, leading to a rapid onset and peak of dopamine levels.
- Methamphetamine causes dopamine levels to drop below baseline, increasing the risk of addiction and psychotic episodes.
- The speed at which dopamine levels increase and decrease is crucial in determining the addictive and psychotic potential of a drug.
Recreational Use, Addiction & Psychosis; Habituation
Recreational use of stimulant drugs like Adderall and Modafinil can lead to addiction and an increased risk of psychosis. People who take these drugs without a prescription are at a higher risk compared to those with ADHD who are prescribed these medications. The dopamine response in individuals without ADHD is much higher and can result in euphoria and heightened focus. It is strongly advised against using these drugs unless prescribed by a physician for the specific purpose of treating ADHD. Starting with a low dosage is common practice to minimize potential risks.
Key points:
- Recreational use of stimulant drugs can lead to addiction and psychosis
- Non-prescribed use of these drugs carries higher risks compared to prescribed use for ADHD
- Individuals without ADHD experience a stronger dopamine response, leading to euphoria and heightened focus
- It is strongly advised to only use these drugs under medical supervision for ADHD treatment
- Starting with a low dosage is recommended to minimize risks
Recreational use, addiction, and psychosis are important considerations when discussing the use of stimulant medications like Adderall and Modafinil for ADHD. The response to these drugs can vary among individuals, with some people needing to increase their dosage over time while others may even decrease it. However, repeated use of these drugs by individuals with ADHD leads to a decrease in the peak effects of dopamine, a process known as habituation. This does not mean that the person becomes completely desensitized to the drug, but rather that the brain and body adjust to the elevated levels of dopamine and norepinephrine by strengthening the connections between neurons. This normalization of the system reduces the need for increased dopamine and norepinephrine levels. It is important to understand that the initial response to a drug is different from the response after repeated use. This highlights the need to consider habituation when discussing the effects of these medications.
Key points:
- Individuals with ADHD may need to adjust their dosage of stimulant medications over time
- Habituation occurs with repeated use, leading to a decrease in the peak effects of dopamine
- Habituation does not mean complete desensitization, but rather a normalization of the system
- The brain and body strengthen connections between neurons to adapt to elevated dopamine and norepinephrine levels
- Habituation reduces the need for increased dopamine and norepinephrine levels over time
Drug Holidays; Ritalin & Long-Term Effects
The concept of drug holidays for children with ADHD taking stimulant medications like Ritalin is discussed. The current pattern of intake for many children with ADHD does not follow the original schedule of taking these drugs during the school week with weekends off. The long-term effects of these medications are not well understood, but there are studies suggesting improvements in executive function for both children and adults who have taken ADHD medications.
Modafinil, Armodafinil; Side-Effects
Modafinil and Armodafinil are non-amphetamine treatments for ADHD, with Modafinil being more expensive than Armodafinil. Generic versions of these drugs are just as effective as brand name drugs. They are prescribed for narcolepsy, dementia-related sleepiness, post-surgery anesthesia, traumatic head injury, and stroke. However, they may not be ideal for learning new material. Side effects include decreased appetite, runny nose, headache, and skin rashes. There is a rare but potentially fatal condition called Stevens-Johnson syndrome associated with these drugs. The approval process for drugs is questioned. The use of these drugs in children with ADHD is a topic of discussion, emphasizing the need for caution.
Guanfacine, Alcohol
Guanfacine is a non-stimulant medication used to treat ADHD and lower blood pressure. It activates pathways that dampen down the sympathetic nervous system, making it less commonly prescribed due to its tendency to cause sleepiness. However, a small subset of individuals, including children, experience significant relief from ADHD symptoms and tolerate guanfacine better than other drugs. Guanfacine works by stimulating the alpha 2A receptors in the locus ceruleus, increasing the salience and relevance of stimuli and activating prefrontal cortical networks.
- Guanfacine is a non-stimulant medication used to treat ADHD and lower blood pressure.
- It activates pathways that dampen down the sympathetic nervous system, causing sleepiness.
- Some individuals, including children, experience significant relief from ADHD symptoms with guanfacine.
- Guanfacine stimulates alpha 2A receptors in the locus ceruleus, enhancing stimulus salience and activating prefrontal cortical networks.
ADHD Medications
ADHD medications, such as stimulants like Adderall and Modafinil, raise arousal levels and reduce hyperactivity and impulsivity. They act on neuromodulator systems to create neuroplasticity and change neural connections. Short and long-term effects are discussed, along with concerns about abuse and addiction. Combining drug treatments with behavioral protocols and working with a knowledgeable psychiatrist is emphasized.
