About This Presentation

Description : Check out this medical PowerPoint presentation titled "Newly Diagnosed Ataxia" by Pravin Khemani, MD, FAAN.
This medical PowerPoint presentation talks about Ataxia, a neurological condition that affects a persons ability to coordinate their movements.
Ataxia is caused by damage or degeneration to the cerebellum or other parts of the nervous system that control movement. Ataxia can affect a persons ability to walk, talk, eat, and perform other daily activities.
Symptoms of ataxia can include difficulty with balance and coordination, slurred speech, tremors, difficulty with fine motor skills, and abnormal eye movements. The severity of symptoms can vary depending on the underlying cause of ataxia and the extent of damage to the nervous system.
Ataxia can be caused by a wide range of conditions, including genetic disorders, infections, tumors, stroke, and traumatic brain injury. Treatment for ataxia depends on the underlying cause and may include medication, physical therapy, speech therapy, and assistive devices to help with mobility and daily activities.

Objectives Symptoms Diagnosis and Causes of Ataxia Multidisciplinary treatment Research
Slide 5-

Symptoms of cerebellar ataxia Ataxia is a combination of symptoms due to progressive deterioration of the cerebellum and its connections: Fogel & Pearlman, NATURE CLINICAL PRACTICE NEUROLOGY, 2006
Slide 6-

Symptoms of cerebellar ataxia Cerebellar Motor symptoms Vestibular (relating to inner ear) symptoms Cognitive and psychiatric symptoms Manto, et. al. Cerebellar Ataxias-an update, Curr Opin Neurol, 2020
Slide 7-

Symptoms of cerebellar ataxia Motor Symptoms: Impaired walking(“walking like a drunk”) Poor balance (falls) Clumsy hands Slurred speech Stiffness and slowness Swallowing difficulty Subramony & Xia ‘Ataxic and Cerebellar Disorders’. Bradley’s Neurology in Clinical Practice. 2016. 7th Ed
Slide 8-

Symptoms of cerebellar ataxia Vestibular Symptoms: Dizziness, vertigo Poor balance (falls) Visual impairment Blurred vision, double vision, “jumping’ vision Subramony & Xia ‘Ataxic and Cerebellar Disorders’. Bradley’s Neurology in Clinical Practice. 2016. 7th Ed
Slide 9-

Symptoms of cerebellar ataxia Cerebellar Cognitive Affective Syndrome: Emotional problems Mood dysregulation Impulsivity Disinhibition Apathy Anger and Irritability Cognitive impairment Planning and sequencing Language Memory Reasoning Schmahmann & Sherman, The Cerebellar Cognitive Affective Syndrome, Brain, 1998 Adamaszek, et. al, Consensus Paper: Cerebellum & Emotion, Cerebellum, 2017

Other clinical features Depends on the type of ataxia Ophthalmological Musculoskeletal Neuropathy Pain Vital organs Cancers
Slide 11-

Causes of Cerebellar Ataxia Neurodegenerative ataxias Genetic Sporadic Acquired ataxias Strokes Infections Brain Tumors Autoimmune (related to known antibodies) Cancers Vitamin Deficiencies Drugs Toxins (Alcohol) Khemani, P: https://practicalneurology.com/articles/2013-mar-apr/overview-of-adult-onset-cerebellar-ataxia, 2013
Slide 12-

Deterioration of Cerebellum and its connections Progressive ataxic symptoms Predominantly cause neurological symptoms Affect primarily the brain and its connections to other organs

Diagnosis of Cerebellar Ataxia Neurologist (who has experience with the ataxias) Thorough History and Examination Known family history of ataxia Genetic testing No known family history Testing informed by the clinical course

Slide 16-

Idiopathic or Unknown ataxia Upto 20% cerebellar ataxias may not have a known cause even after extensive testing: ? Genetic ? Autoimmune ?Sporadic: Related to rare nongenetic neurodegenerative disorders Progressive supranuclear palsy Hadjivassiliou, et. al., Causes of Progressive Cerebellar Ataxia: Prospective Evaluation of 1500 Patients, Journal Neurol Neurosurg Psychiatry, 2017
Slide 17-

Multidisciplinary Treatment of Cerebellar Ataxias All ataxias are treatable A few cerebellar ataxias have specific drug treatments Knowing cause of ataxia informs treatment Treatment is tailored to individual needs Multidisciplinary team approach Gandini, et. al., The neurological update: Therapies for cerebellar ataxias in 2020, J Neurol, 2020
Slide 18-

Treatment of Cerebellar Ataxias Specific treatment for ataxias causing deficiency of vital chemicals Several Off-label drugs To treat ataxia and its symptoms Looking forward New drugs to slow the progression Genetic treatment for specific mutations Stem cell treatment Transcranial Magnetic stimulation and transcranial direct current stimulation Perlman, S, Update on the Treatment of Ataxia: Medication and Emerging Therapies, Neurotherapeutics, 2020 Gandini, et. al., The neurological update: Therapies for cerebellar ataxias in 2020, J Neurol, 2020
Slide 19-

Case Study 25-year-old man Mild gait and balance problems started in early 20s No family history of ataxia 1/4 children Blood tests, spinal fluid testing was normal MRI spinal cord showed possible atrophy Genetic testing revealed Friedreich Ataxia (FA)

Slide 22-

Case Two 55-year-old woman Concerns: progressive walking and balance problems Started in early 50s No family history of ataxia Genetic tests were normal All other tests were completely normal
Slide 23-

Case Two Over the next 4 years Progressive slurred speech, balance problems, falls Urinary frequency, urgency and incontinence Light-headedness Slowness of Movements Acting out of dreams Completely dependent on husband for most tasks due to imbalance
Slide 24-

Case Two Extensive testing, including genetic tests were normal Specialized neuroimaging showed abnormalities in basal ganglia structures Diagnosed with Multiple System Atrophy-Cerebellar subtype (MSA-C) Palma, et. al., Diagnosis of multiple system atrophy, Autonomic Neuroscience: Basic & clinical, 2017
