A structured, short-term treatment designed to optimize cognitive functioning and emotional well-being.

Neurocognitive difficulties can arise from conditions like ADHD, post-infection (e.g., long COVID or Lyme Disease), post-concussive syndromes, epilepsy, Parkinson’s disease, cerebrovascular conditions, and medication-related effects (e.g., chemotherapy). These challenges often impact work, school performance, and self-esteem, creating a cycle of poor mood and worsening cognitive function.

At Acheron, we break this cycle through Cognitive Remediation Therapy (CRT) - a structured, evidence-based approach that enhances cognitive skills and emotional resilience.

Cognitive Remediation Therapy (CRT)

Cognitive Remediation Therapy (CRT) targets areas of cognitive dysfunction through teaching strategies to support strengths and compensate for areas of cognitive weaknesses.

Ketamine-Assisted Cognitive Remediation Therapy (CRT-K)

A powerful integration of cognitive remediation, cognitive behavioral therapy, and ketamine’s neuroplastic effects to accelerate and enhance insight, creativity, and clarity of thinking.

Seamless Neuropsychological Testing & Treatment

All In One Place

At Acheron, we provide both neuropsychological testing and neurocognitive treatment in one seamless experience—so you can receive all your neurocognitive care in one place.

Our neuropsychological evaluations help clarify cognitive difficulties in the areas of attention / concentration, memory, problem solving, language, and emotional regulation – and provide a clear path forward. Led by board-certified neuropsychologist Dr. Taylor Armstrong, each evaluation can provide critical insights into an individual’s cognitive, emotional, and behavioral functioning, and help differentiate between neurological and psychological contributors to symptoms.

In completion, clients receive a comprehensive report that outlines cognitive strengths, areas for growth, contributing factors to cognitive challenges, and tailored treatment suggestions.

This diagnostic clarity from neuropsychological testing can be used to guide neurocognitive treatment—including Cognitive Remediation Therapy (CRT), CRT with ketamine (CRT-K), or another targeted intervention within our integrated neurocognitive program. We move with you from assessment to action, so you don’t waste time stuck in the system.  These services can also occur separately so that you can choose according to your needs.

What CRT Includes

  • Focus and attention exercises, metacognitive tools for planning, goal-setting, decision-making, and time management. Learn to identify and reduce both internal and external distractions.

  • Cognitive-Behavioral Therapy (CBT): Targets self-messaging that contributes to a negative sense of self, depression, and anxiety as well as behaviors that are not conducive to optimal functioning.

  • Personalized Goals: CRT integrates CBT to improve focus, memory, and problem-solving while building awareness and resilience.

  • 9-Session Program: Includes a 1-hour intake session followed by integrated exercises to enhance attentional control, strategic problem-solving, self-efficacy, and self-awareness, promoting cognitive resilience.

  • End Goal: Develop an empowered sense of self by recognizing natural cognitive strengths and develop strategic tools to optimize cognitive functioning in daily life.

CRT also supports those seeking non-medication-based cognitive enhancement, including individuals exploring stimulant reduction for ADHD. While an ADHD diagnosis has been associated with health risks, many individuals also consider reducing or stopping stimulant use due to supply shortages, dependency concerns, and potential side effects, such as mood changes or cardiovascular risks. Having a non-pharmacological option for managing attentional difficulties can be a valuable alternative.
