✓Well SupportedAlpha-GPC is a non-stimulant that can improve cognitive performance and focus, particularly in age-related cognitive decline.✓Well SupportedA threshold of 300 mg of DHA per day is an inflection point for observing attentional effects from omega-3 supplementation.✓Well SupportedIndividuals with ADHD often underestimate time intervals, leading to lateness and difficulty focusing, which is consistent with their typically lower dopamine levels.✓Well SupportedRitalin and Adderall are stimulants that treat ADHD and narcolepsy by increasing dopamine.Partially Supported

Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.

Ritalin increases dopamine and norepinephrine/adrenaline.

✓Well SupportedIndividuals with ADHD often use stimulants like coffee, which may be an attempt at self-medication.

✓Well SupportedIn typical individuals, the default mode network and task networks are anti-correlated, unlike in individuals with ADHD.

✓Well SupportedOptimal use of ADHD medications involves combining them with behavioral exercises and potentially tapering off the drugs.

◐Partially SupportedDopamine controls the rate of blinking, which in turn influences attention, focus, and the modulation of time perception.

◐Partially SupportedMany attention issues attributed to ADHD may be induced by phone use, and the solution lies in changing one's relationship with their phone rather than using medication.

◐Partially SupportedBlinks reset our perception of time immediately after they occur.

◐Partially SupportedDopaminergic compounds like Ritalin, Adderall, and Modafinil are prescribed to treat ADHD by increasing dopamine levels.

◐Partially SupportedElyroine is typically taken in doses of 500 to 1,000 milligrams, with dopamine levels peaking 30-45 minutes after ingestion.

◐Partially SupportedSubstances that increase dopamine levels can lead to calmer behavior and improved focus in children with ADHD.

◐Partially SupportedIndividuals with ADHD may pursue dopamine-increasing compounds like cocaine, coffee, or cigarettes to self-medicate and improve focus and decision-making.

◐Partially SupportedAcetylcholine from the pontine tegmental nucleus and basal forebrain activates brain locations and brings about focus.

◐Partially SupportedLimiting smartphone use to 60 minutes per day for adolescents and two hours per day for adults is one of the best ways to maintain focus.

◐Partially SupportedPhosphatidylserine at 200 mg/day for 2 months reduced ADHD symptoms in children, enhanced by co-administration of omega-3 fatty acids.

◐Partially SupportedThe ability to succeed in life is proportional to one's ability to focus and deliberately defocus when appropriate.

◐Partially SupportedConsumption of omega-3 fatty acids can positively modulate systems for attention and focus.

◐Partially SupportedPeople with ADHD often have challenges with time perception, but can perceive time well when given a deadline.

◐Partially SupportedNeuroplasticity is highest in childhood and tapers off after age 25, with exceedingly high levels from age three to 12 or 13.

◐Partially SupportedThe low dopamine hypothesis of ADHD suggests that insufficient dopamine in specific brain circuits leads to unnecessary neuron firing.

◐Partially SupportedFocusing on a visual target with controlled blinking and varying distances of focus can enhance elementary school students' ability to focus on other information.

◐Partially SupportedL-Tyrosine is an amino acid used to improve focus by acting as a precursor to dopamine.

◐Partially SupportedConsciously dilating and contracting one's gaze can train open monitoring to attend to and recognize multiple targets.

◐Partially SupportedWorking memory is often disrupted in individuals with ADHD.

◐Partially SupportedAttention, focus, and concentration are essentially the same concept for the purpose of discussing ADHD.

◐Partially SupportedPanoramic vision uses a separate neural circuit from the eye into the brain, allowing for a wider angle view and better processing of things in time with a higher frame rate.

◐Partially SupportedIndividuals with ADHD struggle to engage attention for tasks they do not find intrinsically motivating.

◐Partially SupportedPeople with ADHD can experience hyperfocus on enjoyable activities.

◐Partially SupportedIndividuals with ADHD typically exhibit poor attention, high impulsivity, distractibility, and can be easily annoyed.

◐Partially SupportedAbout half of children diagnosed with ADHD will resolve with proper treatment, while the other half typically do not.

◐Partially SupportedA 17-minute session of panoramic vision can reduce attentional blinks and improve focus.

◐Partially SupportedADHD stimulant medications can provide excellent relief for many individuals when prescribed at appropriate dosages by a qualified medical professional.

◐Partially SupportedPhysical movements performed before visual focus tasks can help children eliminate the desire to move, enhancing their ability to sit still.

◐Partially SupportedEyelid shutters regulate information entering the nervous system and focus attention.

◐Partially SupportedDopamine release in the brain is associated with heightened focus, narrowed perception, and increased focus on external stimuli.

◐Partially SupportedLower dopamine levels are associated with a broader perception of the environment.

◐Partially SupportedDopamine regulates the activation of the default mode network and task networks to ensure they remain anti-correlated.

◐Partially SupportedDopamine release narrows auditory and visual focus, creating a cone of auditory attention and a tunnel of visual attention.

◐Partially SupportedCell phones may erode attentional capacities.

◐Partially SupportedLow-dose amphetamine medication, modulated as children grow, can benefit more children than not.

✕Not SupportedElyroine can cause euphoria, jitteriness, or excessive alertness, impairing focus, and should be approached with caution, especially by individuals with psychiatric or mood disorders.

◐Partially SupportedRitalin (methylphenidate) is chemically similar to amphetamine, and Adderall is a combination of amphetamine and dextroamphetamine.

◐Partially SupportedCocaine may heighten focus in individuals with ADHD.

◐Partially SupportedStimulant medication for children diagnosed with ADHD can artificially induce a state of focus, enabling them to learn what focus is and develop the ability to concentrate even when not intensely interested.

◐Partially SupportedImpulse control requires the suppression of sensory events and is separate from attention and focus.

◐Partially SupportedADHD diagnosis should be carried out by a psychiatrist, physician, or well-trained clinical psychologist.

✕Not SupportedStimulant medications like Adderall, Modafinil, Armodafinil, and Ritalin can cause cardiovascular problems by increasing heart rate and constricting blood vessels.

✕Not SupportedPrescription stimulants like Ritalin, Modafinil, Armodafinil, and Adderall carry a high propensity for addiction and abuse.

✕Not SupportedAmphetamines and cocaine can cause sexual side effects due to vasoconstriction.

◐Partially SupportedModafinil and armodafinil are gaining popularity as alternatives to Adderall and Ritalin for staying awake and increasing focus, and are used by the military, first responders, and college students.

◐Partially SupportedAttentional blinks may occur more frequently in individuals with ADHD.

◐Partially SupportedLow dopamine levels are associated with increased neuronal firing in attention-governing networks, known as the low dopamine hypothesis for ADHD.
