SMRITILOPA (ALZHEIMER'S DISEASE)

SMRITILOPA (ALZHEIMER'S DISEASE) - ETIOPATHOGENESIS, DIAGNOSIS AND PRINCIPLES OF MANAGEMENT

• Smritilopa is a term in Ayurveda which refers to loss or impairment of memory.

• In modern medicine, this condition closely correlates with Alzheimer’s Disease (AD), a progressive neurodegenerative disorder leading to cognitive decline.

• Smriti (memory) is one of the manasika bhavas, and its proper function is governed by Sattva guna, medha, pragya, and proper functioning of manas and buddhi.

ETYOPATHOGENESIS ACCORDING TO AYURVEDA

• Smritilopa occurs due to vitiation of mana, buddhi, atma, and indriyas.

• Primarily caused by vitiated Vata, especially Prana Vayu, along with involvement of Tarpaka Kapha and Sadhaka Pitta.

• Weakness of Medha dhatu and Majja dhatu is involved.

• Excessive indulgence in Rajasika and Tamasika ahara-vihara, mental trauma, ageing, and chronic systemic diseases aggravate Vata and impair brain function.

ETIOPATHOGENESIS ACCORDING TO MODERN MEDICINE

• Alzheimer’s Disease is characterized by progressive neuronal degeneration in the brain, especially in the hippocampus and cerebral cortex.

• Etiological factors include:

  • Beta-amyloid plaques and neurofibrillary tangles (Tau protein)

  • Cholinergic neurotransmitter deficit

  • Oxidative stress and mitochondrial dysfunction

  • Genetic factors: Presence of ApoE4 allele

  • Environmental and lifestyle factors: smoking, head trauma, depression

RISK FACTORS

• Advanced age

• Family history of Alzheimer’s

• Hypertension, diabetes, dyslipidemia

• Obesity, sedentary lifestyle

• Social isolation and depression

CLINICAL FEATURES

• Gradual onset and progressive decline of:

  • Recent memory loss (initially)

  • Impaired judgment and abstract thinking

  • Disorientation in time and space

  • Language and communication difficulties

• In late stages: complete dependency, incontinence, and bed-ridden state

DIAGNOSIS

AYURVEDIC DIAGNOSIS:

• Based on Lakshana, Dosha-dushya sammurchana, Manasika dosha avastha.

• Assessment of Manasika bhavas and dhatu kshaya, especially Majja dhatu.

MODERN DIAGNOSIS:

• Mini-Mental State Examination (MMSE)

• Montreal Cognitive Assessment (MoCA)

• Neuroimaging: CT/MRI showing cerebral atrophy

• PET scan to detect amyloid accumulation

• CSF biomarkers: decreased Aβ42, increased tau protein

• Neuropsychological testing for memory, attention, language

PRINCIPLES OF MANAGEMENT ACCORDING TO AYURVEDA

• Nidana Parivarjana – avoidance of causative factors

• Vatahara Chikitsa – balancing aggravated Vata
